see it click it facebook advertising Manchester, Other

Our car body shop was contacted by a sales person (very friendly) offered one months advertising on facebook. we were told they would ring us 3 days before end of month to ask if we wanted to continue with advertising.
Did not get call, I emailed and telephoned to cancel on day contract ended. They refused to accept cancellationas it had to be by recorded delivery. Found out they had set up direct debit on my business card so I could not cancel direct debit without cancelling card completly. When I complained

I was constantly put on hold for 30 -40 minutes at a time, calls were not returned, staff were very rude. HR department or managing director did not reply to my compaint when I put it in writting.No one I know on face book saw the supposed advert, when I questioned this I was told a person would have to use the key words up to 17 times before the advert would appear. Eventually I beleive they blocked my email address as emails were undelivered. Be ware of this company.
