I had XXXX in XX/XX/XXXX/XX/XX/XXXX then ended my services with them in XX/XX/XXXX. The sent me a bill dated XX/XX/XXXX showing : Bill Amount : $ XXXX & Payment Due Date : XX/XX/XXXX Then the following I got a bill for them for an equipment, which my husband had taken back. I sent XXXX XXXX XXXX XXXX a dispute letter. A manager called me and asked to speak with my husband to verify ; I told him that my husband had died XX/XX/XXXX. He apologized and he would close the account because my balance was actually a credit. Now this year I found this account on my creidt report from AFNI a collection agency with a balance of {$780.00}. I have tried without success to convey to this agency that this is a mistake to no avail.
