They continued to bill me for a year after I transferred my service, then told me that they can't issue more than 3 months worth of credit. I asked if the calls are recorded, so they could go back and here me explicitly tell the rep that I had bought a house and would be needing service at the new house instead of at the apartment. The supervisor that I talked to didn't even flinch when I said that I wanted to cancel my $150/month plan because of their unwillingness to credit the full year worth of charges (about $300). I should not have to pay for their rep's incompetence in handling a simple request to cancel service at one location and begin it at another. I was told that it's my fault for paying it. Then, I was told that I should have called them earlier.
