Just Fitness 4 U review: Billing

I signed up with this gym in January of 2011 before the facility even opened. I was told that after my two year contract expired, I would continue to have a membership even though I would not be making any more monthly payments. I would only be obligated to pay a once a year account maintainance fee. Well, now it's two years later and I spoke with the finance company called ABC Financial http://www.abcfinancial.com/ and they told me that that was in fact not true. I would be out of my contract but would pay my regular payment of $21.64 on a month to month basis. I then contacted the manager at the local gym that I go to named Dan and he assured me that he would call ABC and clear it up. No payment was drafted from my account in February so I assumed everything was taken care of. Then, I check my account this morning and they've drafted a payment of $54! My payment was NEVER $54, so I looked up my account details on ABC's website and it shows that they took a payment of $49 for who knows what and a late fee of $5! A LATE FEE! They've been drafting my payments this entire time. How could they possibly charge me a late fee, especially when it's on an amount that I don't even owe! I tried calling ABC but they're closed on the weekends, and I can't get a hold of the manager at the gym either. I am SO irritated! I'm not the only one they did this to either. Two of my other girlfriends who joined at the same time I did noticed the same thing, except one of them had a payment of $49 AND a payment of $54 drafted! I just hope I can get this straightened out and get my money back! Ridiculous!
