Wrong Verizon charge reported to credit bureau
A few weeks ago I received a letter from a debt collecting company regarding my old Verizon account. The letter stated that I had an outstanding payment due of $82.29. This balance was mistakenly created by Verizon making duplicate charges dated on 11/30/2015 when they charged the same amount twice for a refund check for my outstanding credit. Basically I overpaid when I disconnected the service in my previous house and was entitled to a refund. I only received one refund check of $82.29 and the Verizon's payment history shows two payments (each of $82.29) of were issued on 11/30/2015. Basically, Verizon thought they paid me twice when I only received one check. Since the time I saw that, I called Verizon multiple times to correct the error, but they simply said they could not help me because the case had been transferred to debt collectors. When I received the letter from the first debt collector I disputed as was instructed and received no response. A few days ago I received another letter from a different debt collector, and I sent a certified letter to disput as well.
Then today suddenly I saw the "debt" showed up in my credit report as a negative case and it made me furious.
Every time I tried to resolve this issue with Verizon directly, I was told they can do nothing because the case is with debt collectors. So, I responded to the debt collectors as instructed, and now I see it showing up in my credit report? If Verizon keep me pushing me to the debt collectors and do not even try to take look at what happened, how can I fix the wrong debt created by Verizon's mistake?
I am still Verizon Fios customer, but this is getting me more and more angry. How can you fix this problem?
