Salvatore Logiudice Master Tentaka fraudulent transaction on the internet Internet

I recently purchased a membership to a site hosted on your network .  
I received a login but it did work.  I informed the webmaster (using two e mail address) 
and the credit card processing company but received no reply. 

I have emailed them on a further four occasions but again without reply.  
The money has been taken from my account but I have not received a working password. 

I have tried ringing but get no answer.  They do not appear to respond to any form of communication.
They are at best unprofessional, at worst scam artists.  
I really thought the net had got rid of the cowboys and scum.
