Leisure Stay Group
Paid for Service, now i'm being ignored

I Received an invoice for a special that Leisure Stay Group are offering to place accommodation on 7 websites. since making the payment in May I have been completely ignored, I have sent emails, tried contacting them from the web page. the phone number on the invoice only goes to an answering service. no contact phone number is advertised on the web page. it this just bad business service, or have we been?? If its a it must be reported.
