AT$T, the WORST cell Co. ever. Period. They refuse to immediately cancel service and unlock my phone

So just to start off I have been a member w AT&T consecutively since 2014-now (not counting the 2, 2 year contracts I did b4 then and swapped or canceled services. I also just got hit with TWO months of billing when I cancelled my service two months ago, called and said hey my contacts been up over a year, I cancelled and rather than spending 100$ a month I spent 30$ on a "prepaid sim" I asked them to verify my # linked to my act hasn't been in use. The dumb lady kept saying the words "contract (again even tho my device and contract have been up since Oct 6th 2015)" and "it's our policy" while avoiding helping and refuses to let me speak with a manager. I hope they fire you Shanuiqa or Sasquatch or whatever ur stupid name was. Ok so on to the most important part. I need to unlock my cellphone to use with Verizon cuz AT&Duke has ZERO bars in podunk town Wa. But guess what even tho I cancelled my act two months ago I have to do it again, but the real gem is "as a curtesy ur act will stay active for two additional weeks, idgaf! I can't unlock my PAID FOR IPHONE cuz ur amazing awesome bul$hee of a "unlock portal" won't realize that my act is cancelled and every request I submit and wait two effin days per time I just get this Downs's auto reply saying " opps looks like that device is still active on a account plz try again later" ......... called them about 20 times now, seriously has been the WORST experience ever. Do ur self a Huge favor... if ur only choice is to stab ur eyes and ears out with a dull rusty aid laiden nail or sign up with AT&T, take the nail. Live ur life happy knowing you absolutely made the right choice! Crap employees, trained crappily by crap managers who answer to crap ceos and "investors" even tho they sucked 100$ a month outta me for years, the second you need help or have a prob. Forget about it, that's against "their policies"
