Clear Clearwire After Cancellation Completed, Stole Money from Debit Card Internet

I cancelled my service.  Two weeks later I received a call from a Clearwire agent, requesting the security code from my debit card so that she could process the termination fee.  This was the debit card they had been billing me from for some months for my service, so I found it weird they would need a security code at this point.  The termination fee was not a problem, because I was aware of it when I signed up for the service.  The problem was, I had cancelled two weeks ago, explicitly acknowledging the fee with the agent at that time, and they had called me twice since then with annoying surveys to try to regain the account.  They were finally calling me again to authorize the termination fee, when they could have run it through two weeks ago.  Perhaps they waited for the hardware I had leased from them to arrive back at their warehouse.  If this was the case, they could have simply sent me a courtesy email and billed the card without forcing me into a conversation.  It is repugnant for a company to force an ongoing relationship with a customer who has cancelled.  But this was just the beginning.

A month later I received an email from Clearwire informing me of a charge.  I looked at my bank account and Clearwire had made two completely unauthorized charges days/weeks after processing the termination fee.  Most likely these were due to an internal error in their system for accounting for customers who provide some or all of their own equipment, rather than leasing from Clearwire.  In any case, it is my belief that agents of Clearwire were aware of this potential error before it happened; in multiple conversations agents assumed I was leasing equipment which I actually owned, and on these occasions I corrected them; at this point they should have ensured that I would not be billed improperly.  Furthermore, one of the unauthorized charges was not accompanied by an email to my account.  After calling in, I was told I would receive a refund the next day; the refund did not come, and only after an online chat with a representative did I discover that this would take several days.  At this point I asked the representative to provide me with written documentation acknowledging that I was making a written request, because a written complaint is required by Clearwire within 30 days or the customer forfeits the right to a refund on an errant charge.  The agent politely apologized, stating the transcript of our chat could not be emailed to me, and that I would have to file my complaint with a different department.  I have been a captive audience for their departments long enough, so I simply captured a screenshot of our chat log.  Tell all of your friends that Clearwire does not respect the bank accounts of its former customers!
