Product: Debt collection

On XXXX/XXXX/XXXX, I ordered a rose gold colored IPhone from XXXX through their web tele sales department. I signed up for a financial product termed " payment plan '' to pay the phone over time and was to be charged {$50.00} for taxes. The XXXX new account was XXXX. XXXX shipped the wrong phone ( my order was recorded ). I called and was told that the rose gold was a popular color and would not be available until 6 weeks. I told them I would sent back the phone because I did not want a phone that I did n't order. They attempted to force me to the sale but I shipped the phone in their remorse policy return UPS package. 
On XXXX/XXXX/XXXX, XXXX received the phone back as evidenced by XXXX tracking number XXXX. 
On approximately XXXX/XXXX/XXXX, at approximately XXXX, I called XXXX ( possibly spoke with XXXX ) to complain for receiving a usage bill from XX/XX/XXXX through XX/XX/XXXX for {$95.00} though I did not have a phone and cancelled during the remorse period. The agent said the rose gold was in and that she would get me an even better deal if I signed on again with XXXX. She emailed a contract for an entirely DIFFERENT financial product. Instead of a payment plan, XXXX attempted to trap me into a " lease '' which effectively termed me into a contract I could not get out of. I did not sign the document. Instead, I called XXXX at XXXX the same night and spoke with XXXX in buyer 's remorse department as well as XXXX in customer service. I complained about the bait and switch with the second attempt to contract me with no phone and complained about the {$95.00} charge for a period when I did not have a phone. XXXX said she took care of the refund for the {$95.00}. 
On XXXX/XXXX/XXXX, 13 days after I returned the phone and cancelled the service, XXXX aggressively and without my consent withdrew {$51.00} out of my personal bank account for a phone that had been returned and was never active. On XXXX/XXXX/XXXX, I called XXXX to complain. I spoke with XXXX in retail support who confirmed that XXXX received the returned phone on XXXX/XXXX/XXXX. I asked to transfer to a supervisor. I spoke with XXXX at retail support who transferred me once again to XXXX sales who XXXX said handled all refunds. I was told that I would have the tax money for the phone I did not have and the charges for the use of phone which I never used returned. The taxes were returned on XXXX/XXXX/XXXX. 
On XXXX/XXXX/XXXX after receiving another random bill for {$68.00}, I spoke with XXXX in customer service. I told her that I received the letter acknowledging that I cancelled service with XXXX but they are still billing me. She said the adjustment was set up to come off tomorrow on XXXX/XXXX/XXXX. 
On XXXX XXXX, XXXX, instead of receiving a " paid in full '', XXXX began harassing me with collection of past due notices. This time, the " random '' amount that I was billed increased by XXXX percent to a balance of {$690.00}. 
On XXXX XXXX, XXXX, I received another bill in the amount of {$690.00}. 
Although all XXXX representatives, and I 've only named the ones I have written down, agreed that I had returned the phone and was released from contract and the tax money was returned to me, XXXX continues to harass me by sending debt collection bills and recently have amplified their threats through a debt collection agency. 
On XXXX XXXX, XXXX, AMSHER Receivables Mgmt called me while at my place of business indicating that they were debt collectors. I do not owe any debts and have not received correspondence from AMSHER. I asked them not to call me at work. Through Internet, I learned that AMSHER is a debt collection entity associated with XXXX. AMSHER continued harassing phone calls from the same number on XXXX XXXX, XXXX at XXXX while I was working. Once again, AMSHER rang my phone at XXXX, the same day, while I was working. At XXXX
