Purchased a battery. Battery was no where to the specs that was listed on the page. Was told by support to contact the seller. I did, and the seller didn't respond. Support said they'd take care of it. They asked for evidence of the issue in order to process a refund. I sent them a video showing all the problems. They claimed they couldn't see it. I filmed it perfectly with a high end camera this time. They told me to wait. They then said the seller would handle it. I tried talking to the seller, the seller didn't respond. Support again told me to wait. Then they finally contacted me telling me that I was too late to receive a refund. Their support pretty much scammed me. They did so, so that Aliexpress wouldn't lose the profit on the sale. Do not buy anything from them, and especially anything high priced.
