Conflicting stories

At the end of JANUARY I sent my Samsung note 3 in for repairs of the lcd under the ADH warranty. A month later I was called by Rowina stating that I have to pay for my repair because the back was damaged. My phone was working when I sent it in but now they say it's dead. I asked for an email detailing what exactly is wrong with it. No email was sent. She called me again saying I have to pay because my phone has no serial number, which it did when I sent it in, even had proof of purchase. So the story changed from something being faulty to no serial number. Again I asked for an email of what they want me to pay for. It wasn't sent. She called again asking if I accept the quote of which AGAIN I asked for an email detailing the quote I'm supposed to accept, she said she would send it immediately. It's been a month I am still waiting. Such ********** activities. The calls are apparently recorded so they can tell me exactly why I'm being given conflicting stories and being harassed into accepting a quote over the phone. Still no email from Rowina. Who keeps badgering me into accepting a quote I haven't seen. She left me a voicemail this morning AGAIN pushing me to accept the quote!
