direct marketing inbound telemarketing merchants review: regular and increasing bills on my credit card statement

I keep finding two bills per month from Epoch Belvedere on my credit card statement. They appear to be Direct Marketing Inbound Telemarketing Merchants. The telephone number provided on the credit card statement is +[protected]
I think this is a US number although I am not sure. It could be a California number. It might be in the UK. I have tried phoning this number but without result. Can anyone help me find a contact number and above all help me get rid of the. I cannot afford the nearly £60 a month they are now taking from me.

Please email me on anthony.[protected]@btinternet.com
