Horrible Dell Financial Services issue!

I called in December to get the pay off amount on my computer. The man on the phone told me the amount that it would take to pay off the computer. I asked several times if that information was correct, trying to make for certain that the amount he told was right to ensure I would not have to pay anything else and I would be done with my payments. He assured me that after that transaction that would be the end of it. After reviewing my credit report recently, I noticed Dell had reported me owing them almost $300. I called them tonight, 1/16/12, at around 7 to ask about the report to my credit. The person I spoke with informed me that I still owe them over $300. When I explained what the other man had told me about paying off my account in December, she just told me that what he had informed of me was wrong, that I do indeed owe, and I need to make a payment. I then asked to be transferred to a manager. The manager was completely rude and did not in the slightest bit care about the my problem. After telling him again and again that this was not right, all he had to say was that I stilled owed and I needed to make a my payment and keep my account current, then HE HUNG UP ON ME! To Dell, is this really the type of service you want your customers to experience? Is this really the impression you want to leave?

I was told that I had payed off my computer, then was informed that I still owe money! None of the people I talked with on the phone tonight, or any other time I have ever called as a matter of fact, were in any way helpful or caring of my issue. Not to mention the fact that my credit is now being messed up over THEIR mistake! Dell has the absolute WORST customer service I have EVER experienced, not to mention the way they run their company is HORRIBLE!! I am completely disappointed and will NEVER do business with them again!
