Zone fitness opens account on your behalf without u being there!

I have been recieving calls from zone fitness claiming I had opened an account and is harrasing me for payment, I have not signed a single paper or delt with any sales person of theirs I have spoken to one of their people about this matter telephonic ally the first time they phoned me... I left the matter to them to fix since I have no dealings with them in the first place they still continue to phone me about an account that I have not opened!!!!!!! Please do not accept pple signing up without them providing a if to prove that it's the correct person signing up yall intertaining ********** and leaving us to deal with matters yall have started!
