Inteligator No Refund for cancellation of Account, Internet

I used the service provided at the trial offer of $4.95, and on the same day I cancelled the service.  Four days later my debit card was charged for a monthly subscription to service.  I contacted customer support at Inteligator, asking for a refund.  The smartly written reply was that I did not properly email them for cancellation of account.  I was asked to forward the email which I did in my reply to Adrienne at customer support.  Several days later her or his reply was that I did not forward my cancellation request.  So I have been given the run around for several weeks about this.  Do not use this service.
