Spark Intertrade Co., Ltd. (บริษัท สพาร์ค อินเตอร์เทรด จำกัด)

The service was terrible. I bought a battery, and when it had a problem and I sent it in for checking, they said they wouldn't replace it under warranty, even though it was still under warranty.

I went to get to battery change here 2times already and recieved Very good service with reasonable prices 👍 …

I sent in my handheld vacuum cleaner for a battery replacement on October 7th. The battery issue was fixed successfully, but I’m now facing serious problems with the returned item. The adapter I received back is clearly not the same one I originally sent. Because of this, I’m unable to charge the vacuum cleaner during the entire dispute period. When I tried plugging it in, the connector didn’t fit properly—it wouldn’t stay in place, making charging impossible. After noticing the issue, I contacted customer service and asked for a photo of my package when they first received it. The photo clearly shows that the adapter and wire were in near-perfect, like-new condition (see photo no.1 on the left). When the repair was completed, they initially forgot to send the adapter back, but later returned it separately. Upon receiving it, I found the wire was in completely different condition, and the adapter tip looked different in shape. After checking with their engineer, customer service insisted it was the same adapter I sent. This raises several questions: What happened to the original adapter’s near-perfect wiring condition? Why doesn’t the plug fit my vacuum cleaner if it’s truly the same one? Why does the adapter head look different in shape and design? I work in the machinery business, and I had both my engineers and even non-technical friends examine it—everyone agrees it’s not the same adapter. The one star goes to customer service for at least responding to my messages. The remaining four stars are lost due to poor case handling, the three-week delay, and the engineer’s refusal to acknowledge that the returned adapter was not the same. Apologizing for “damaging” my wire isn’t enough—it’s not just damaged; it’s the wrong adapter. Advice to Others: If you plan to send your item for repair, make sure to take clear photos of every part from all angles and have them confirm receipt with proper documentation. They eventually offered to send me a new adapter, but after all the denials and dismissals, I was too insulted to accept. Instead, I’m sharing my experience here so others can judge for themselves. I'm attaching what I found as to your staff's claim that the adapter sent is mine and for Astina Vacuum cleaner. Can you spot which the adapter you sent back to me and was very adamant that is mine for the past 3 weeks before finally offering to get me a new one. The final offer should have came first with thorough checking (which I kept providing your staff to see the difference yet was replied by that being the only adapter therefore it's ours's). I suggest you check the conversation log I exchanged with your staff to make a better understanding. When the last offer came, I felt like the company's best solution is to buy me off. What's right will always be right. What's right doesn't feel right when bought. Find the truth much be first. Fact no.1 when I got it. It does not plug in. I even provide VDO clips, but to disbelieve of your team still. Today I submit addition al picture for you to see which one I think you sent me. I trust that you can search for pictures for the adapter for my vacuum machine(AV-9S IRIS) and then do an actual assessment. I hope things will improve internally as I do know the Spa brand of battery if a good brand that's why I choose your brand in the first place. Thank you for the offer again on a new adapter, but I must once again decline. Reason being that the offer wasn't made with the right intent. I have already ordered the correct for it.

The staff were excellent. They called the company, and asked us to add them on LINE, send photos and details of the item we wanted repaired, get a price estimate, and provide our location for them to come to the office. The parking was a bit unusual, but it was well managed considering the space limitations. The staff received the item and updated us on the progress via LINE. I appreciated their honesty in explaining the reason why the item couldn't be repaired.

I bought a motorcycle battery and it works great. It's well worth the price and offers good value.

The staff provided good service, and the products passed quality control (100%).

The advice service was good.

The staff provided good advice. The battery is also okay. I would recommend it.

The product works very well.
