Pay for nothing

So angry with this gym. I have a gym contract that i have not been able to use even once since sighning up in December. They havent even allowed me access once because they say i am not paying despite the fact that they have all the relevant forms and bank details for debit. They say they are not able to debit so i made cash payments then they would not allow me access until the following month in which case they again failed to debit and asked me to repeat that same process again and then again i wasnt allowed. So basically i have paid for something i was never able to use. They wouldnt even give me fingerprint access to something im paying for. I will add reviews to hello peter also. So annoyed with people who just mess around. Now they threaten with legal action! Bring it on
