<prompt> Human: So my husband and I are avid readers of rpersonalfinance and were strongly dismayed to get a letter in March stating our 99 ATT bill had gone to collections... when we have never had an ATT account. So we applied what weve learned from the wonderful people here and quickly sent off a letter via certified mail asking them to validate the debt. Two days ago, we received this letter below stating they cant validate the debt and are removing it from my husbands credit report and are ceasing all collection activity. Prior to reading the posts here, we probably either would have paid it or ignored it, causing a bigger problem. So heres a big thank you to the rpersonalfinance family! Well definitely continue to monitor our credit report to make sure its actually taken off, but it felt amazing to know how to fight against it and win!EDIT: Some people have been asking for the original dispute letter we sent, so here it is: Dispute Letter  <response>: OP here, I tried to edit the post to add the link to our copy of the dispute letter, and the post now says removed. Heres the original text below. If anyone knows how to bring the post back, please let me know:So my husband and I are avid readers of rpersonalfinance and were strongly dismayed to get a letter in March stating our 99 ATT bill had gone to collections... when we have never had an ATT account.
