A couple of months ago, I purchased a new battery for a laptop.
It took a week or so to arrive, coming from China, then after dismantling the laptop, the battery was not recognised. Battery is nominally 11.55v, but only showed just under 1.10th of a volt on each of the three power connections. I've heard that lithium ion batteries, if they get too low, will not accept a charge. Either that, or the management system built in is not compatible with the laptop,
After an email exchange, they sent a replacement, declared known good before despatch. At least the laptop could see this one, but still refused to charge it, and the voltage was similar.
More email exchanges. They agreed a refund, after they received the second faulty battery back. (For some reason, they are not interested in having the first one returned) But, due to a warehouse move, cannot have returns yet. So I'm supposed to wait for the refund.
More email exchanges, they offered 50% refund, then the rest once returned, but still wait. I suggested I'd contact the credit card company for a refund. The company refunded my costs.
Still awaiting return instructions.
Meanwhile, received a Trustpilot review request. I ignored it.
Later, a second review request, so I left an honest review.
Today, they've asked me to delete my review. I said no.
