Camera pairing issue

I've never had a problem with whatever I bought from Epic Deals up until now I bought a xiaomi BW300 camera the camera is fine the issue it doesn't want to pair because it's still linked the previous owner MI home account so it won't pair i called epic deal the consultant and told him the issue i was just told to WhatsApp i did that and even wrote a email since you take forever to reply I'm still waiting for feedback, I'm feed up and disappointed with epic deals I won't buy anything anymore from Epic deals
