Business ProfileforARH Federal Credit Union

I owe for a car loan at the credit union. I called and asked if I could increase my payments by 50.00 to pay the loan off sooner. I explained to them in detail what I wanted. They faxed me a form to fill out and to return. I filled the form out and instead of deducting the amount I wanted they deducted double the amount and increased it by $50. I called them and explained to them the problem and was asked HOW SHOULD WE KNOW WHAT YOU WANTED US TO DO? They said they would issue me a debit card to use until it was cleared up. And then they told me it would be taken care by the next pay period. But they kept going on and on about how I should just keep my business with them that their debit card was so much better than most banks. They said I should just continue banking with them because I would LOVE THEIR BUSINESS IF I WOULD JUST GIVE IT A TRY. I told them I was happy with my bank and wanted it switched to just the payment amount asap. The next pay period they increased the amount by another 310.00 . Which means now my entire check is going to their office on my debit card. After I called them they asked me HAD I CONTACTED THE CORPORATE OFFICE? By this time I'm pretty upset. I asked WHY SHOULD I? ISNT' THAT THEIR JOB. But, every time I call them I can't actually talk to anyone. I get an answer machine they return my phone calls late in the day and explain to me THEY CAN'T PULL THE INFORMATION UP ON THE COMPUTER TO SEE WHAT'S GOING ON BECAUSE THEY HAVE ALREADY LEFT THE OFFICE FOR THE DAY AND ARE JUST RETURNING MY PHONE CALL. This has gone on for months now. I don't like their debit card and don't want them to take anything out of my check by the payment and additional 15 just to cover any added charges. The last time they returned my phone call from their car I said I HAVE BEEN SO PATIENT AND I'M TIRED OF ALL THIS MESS. I said IF THIS ISN'T FIXED BY THE NEXT PAY PERIOD (which was 2 weeks ago yesterday) I AM GOING TO CONTACT THE BBB they told me to go ahead.
