Nothing in writing, in fact I didn't even know I was banned until the manager went crazy saying your banned.

Start of story, around about last year summer time in tesco i checked a cream by taking out a tiny size amount on my finger to check the fragrance and if it was suitable for me. I didn't like it so put it back. On my way out after i had paid for all my shopping i was approached by a manager and a security guard saying i had used the item and i had to pay for it and if i didn't they will call the police, the manager was being overly and unnecessarily aggressive. I was asked to pay for the item which i did and that was that. Or so i thought. just recently I went in to the same store was approached by the same manager who started saying very aggressively again that you are banned from the store and get the f*** out right now or i'll call to police and to be honest it was all quite threatening. i said OK call the police, he ran up to the security guard desk and was on the phone to someone by the time i got there he had gone away into a back room somewhere and didn't reappear after that at all, leaving me with the security guard who didn't have a clue what was going on. The security guard calls another manager They said that the other manager last year had informed me that, after i used a cream without paying for it, that he had banned me from the store and to leave. She said the police are on their way but if you leave that will be the end of the matter. I said i want to wait for the police to arrive so we can sort this matter out, the police didn't arrive as they apparently weren't even called. I wanted to make a complaint about all this, was told to phone tesco head office and complain. Asked for the managers name who "banned" me, and was told we cant give you his name due to the data protection act. All in all I'm very angry at this situation and would like to make a complaint about this but feel it would get me nowhere and i just needed somewhere to vent about this and receive some advice on what to do. Or should i just leave it all behind me? Needless to say i will never be shopping at tesco again.
