I too have issues with BlackView warranty! I was sent a defective phone (half the sensors in my BV6000 were not working). BV told me to settle this with the seller. I sent my defective BV6000 back with tracking # to the seller (http://www.ebay.ca/usr/newteckcity
), seller name on PayPal appears as TOMTOP TECHNOLOGY LIMITED. Seller told me it was lost although it was clearly received by them according to carrier and tracking. I opened a service ticket to report an issue with delivery with my carrier (Canada Post), and was sent a letter after a few weeks that my package was indeed successfully sent and picked up at the post office in China! Anyway seller refuses to refund/respond, after all he has my money, why would he care! At the end, I had to buy another BV6000 from another seller (this one was working fine thankfully). But still, what a poor outcome (more than twice the money spent). I contacted BV about all this and never had a single answer back!
Having known their customer service is so bad, I would never have bought a second phone from BV !
