I sent a few miners to Bitmain in LA for repair last December. I paid BTC per request. Then they asked me to pay BCH after 2 weeks and they said they would refund BTC. Ok I paid BCH. After 3 months they still have not sent the miners back as they promised the miners would be send out within 7 working days. I wonder whether it's only me having this issue or it's typical for repair.

Obviously Bitmain is dumping all the miners and they don't care about the service any more. Dealing with these Chinese companies is really painful. No wonder people would rather pay more on eBay for miners, instead of dealing with Bitmain directly.
