Signed up with tmobile, had a phone and a tablet with data. My tablet kept breaking under manufacturers warranty. I called the manufacturer to send it in for a warranty repair ( which would have been free ( - {$7.00} shipping ). Unfortunately since my tablet had LTE, they told me I have to go through where I activated it to have it replaced. I went to XXXX and they created a service order to get me another sent out. They charged me {$20.00} for shipping and tried to tell me if I had a protection plan it would have been free. I 'm not happy about the {$20.00} shipping vs the {$7.00}. Anyway, I get my tablet and it has the same issue as the first. I go into XXXX, and I 'm hit with another {$20.00} shipping charge ( mind you it 's still under mfg warranty ). I reluctantly paid them again and waited for my new tablet. When it came in the mail, it was cracked in top right corner and bottom right corner. I go to XXXX store and yet again they tell me {$20.00}. I did n't warranty it again that time because thatwould have been {$60.00} to get a warrantied tablet working. Anyway, I decided I was done with XXXX. I called them up to cancel my services and to lay my final bill. The first person that picked up the phone was very unhelpfull, I told him I wanted to cancel my lines, yet he was very persistant to try to keep me as a customer. I refused, and that should have been the end of it. A few months later I realized that he did n't cancel my account and I have been getting billed for tablet data. I call back and the second person that helped me was very helpful, she closed my account fully and she looked over my account, and she told me my final balance. I paid for it over the phone and she told me that everything is payed for and to ignore the next bill in the mail, as todays payment would not show up. Bill shows up and gets ignored like she told me. The bill kept showing up for the same acct. They called me about it. I told them to check their records, everything was payed for. They sent me to collections, so I filed a XXXX complaint. An agent from XXXX called me to inquire on the complaint made by me, I expected him to have my information and history ready. He calls, he tells me I owe {$110.00} for my tablet, I asked him to go through my notes and records on the account, but he told me he did n't have any of that ready, and insisted I pay them. He did no research into my account, and talked down to me. He was n't willing to go through my acct history, and told me to just pay them. Now I get annoying collection calls all day from a XXXX.
