O2 fitness charged my account for an extra month's membership beyond what my original contract with Seaboard Fitness covered. I signed a membership agreement with Seaboard Fitness on 8/18/2010. O2 fitness bought Seaboard fitness before the end of my contract. I stopped attending the gym, but honored the remainder of the original contract. When that contract expired, O2 continued to charge me for another month's membership. When I called to inquire, I was told that O2's policy is to continue charging on a month to month basis after the contract expires. I did not sign a contract with O2, I signed with Seaboard Fitness, whose policy was to ask the patron if the membership should be continued. O2 claims it cannot refund the extra month's charge, even though I did not authorize any additional payments from my account.
