The Social Media people
These people claim not to have received a letter cancelling a Facebook advert and are now trying to run up the bill

I am having a problem with these people, who claim to advertise on Facebook. I cancelled the advert within the specified time but they maintain they didn't receive the letter for another 3 weeks. This then going into another month, hence they want more money. I have now sent a recorded delivery letter inviting them to take me to Court.

Has anyone out there had or are you having a problem with these people?

Many thanks
