ok so it started with the cell company sprint.. they billed me for 3 months of service i didnt have,they sent me to collections and i told them i wasnt paying for service i didnt have.. they reported negative on my credit then sprint hired 2 more collection agents whom also reported negative on my credit for the same bill is this legal.. also i did try and take it up with sprint but they told me that since i cancelled service there is nothing they can do the account is closed.... can i get some thoughts on this?
