I have horrible credit/complete lock of and i am working to fix it. I decided to change service providers and had to pay $800 per line. I started service 9/5/12 and paid a total of $1600.00. I was told I would get it back with interest in 12 months. When can I expect that deposit back? A month after the last billing cycle? 2 weeks possibly?? What is the typical turn around for this??
