<prompt> Human: I purchased the gym membership off someone else and theyve paid transfer fees and everything has been switched over in my name. The contract I signed stated weekly payments of 22.50 but the gym has contacted me saying the price is supposed to be 23.75weekly and that theyve made a mistake. Are they allowed to do that? She said if I dont want to pay the proper rate then shell have to cancel the transfer. Obviously the price difference isnt massive but its the principle. Any advice on what my rights are in this situation would be helpful!  <response>: They owe you whats in the contract for the length of the contract, plain and simple.
