I purchased a phone from a Verizon authorized dealer. Though I returned the purchase within the 30 day period with no penalty, the dealer didn’t update my return causing Verizon to believe that I still owe to them. Verizon has reported this debt to the credit bureaus and since then this has been hurting my credit score. I do have original purchase and return receipts and both Verizon and the dealer admit that they were wrong. Can I sue them?
