Bought a refurbished Poco X3 Pro near the end of May. It only took a few days to arrive. So far so good ! A few days later it suddenly got stuck in a bootloop where it would constantly reboot. Looked it up how to fix it and found out this is a fairly common problem with this model and also with some other Poco or Xiaomi phones. Someone online suggested repeatedly pressing the power button in order to stop the bootloop. A strange solution, but apparently this has worked for some people. So I tried it and it actually worked ! So it happened a few more times. I tried the solution and it worked every time ! Then it stopped happening. I had told Back Market about it and they were very kind and offered a refund. The problem had stopped so I decided to not get a refund for the moment coz I needed to have a working phone at the time in order to get a new place to live, so I couldn't afford to be without a phone. So I decided that if I had more problems with the phone in the future I would then get a refund or replacement or repair. A few months passed without any problems, then it happened once again and I tried the same solution and it worked again ! Thank goodness ! So then a month or so later I was in the middle of using the phone, browsing the web using the Google Chrome app and the phone just switched off and wouldn't turn on again. It is now just an expensive paperweight ! It won't take a charge either ! I contacted Back Market for help in getting a replacement. I also asked if they would be able to upgrade the replacement phone to the 8gb ram, 256 rom model of the same grade and I would pay the difference. That was on August 15th 2023. They have not read my messages or responded yet. They were very fast to reply when I had a problem before, but strangely they are not fast this time or are ignoring me for whatever reason. I thought they had very good customer support before, but now I have to say that their customer support is absolutely terrible !
Desired outcome: I would like an apology and also that they replace my faulty handset with the upgraded 8gb 256gb model of the same grade and I will pay the difference. The phone came with a 12 month warranty, so I know I'm entitled to this.
