Was a customer for 14 years. Decided to switch when they could not provide unlimited data for a reasonable rate. Switched my service. A very short time later I received a bill for $350.00. Thought for a moment and was very certain the phones were paid for. Called company rep on the phone stated it was for a new plan termination. She willingly stated they will credit. Look for it in a few days. I did and no credit. Called back and the rep stated "she should have told you we can'd do that on our end" He informs me to dispute with my credit card. I ask Verizon is NOT going to challenge? He says "No". I dispute and get a credit. Shortly after this I get a collection letter. I contact the collector and inform them I do NOT owe this and stop contacting me. They stop. Verizon turns me over to another collector. Send them a letter advising them of their inappropriate actions and my rights. They stop. Not long after this I notice Verizon puts this on my credit report. I have a spotless credit file. They need to honor what their employees say.
