I called wanting to change my home gym ,I was informed about the transfer fee cost but not that should I decide to change back without even setting foot at the other gym that I will be liable for the costs irrespective.I have asked for the recording where the sales lady explains all these costs.To date I am still waiting and instead keep getting irritating calls that I am owing.I don't have a problem with that,but just feel this is all wrong for them not to divulge such critical information to people .I think that is what the recordings are for as well to prove,otherwise they must cancel this thing as they are spoiling my credit score for no reason .
