Inappropriate deceit

We have had our year end function dinner at Montecasino. My colleagues taken out temporary cards as my card works at certain machines. Upon cashing card to return my deposit was not working. I return to the machine to my surprise my card was blocked. All tried to assist me.Que was long there was no security assistants. I was than sent back to the cashiers and was asked to wait. Roshila called security as i enquired what the problem was she mentioned she not sure. I enquired for my refund on the card do i need to wait so long. She came back saying there was a huge amount on the card hence it was blocked and they will call me. I went for dinner and returned as they called me. Upon my return my card was taken and pictures as they threatened me to sign a document as i explained Mr George theres a misunderstanding. Mr Sifiso explained this is wanted card which i had no idea as someone cashed my card up and they rewarded me enforcing me to sign and banned me. Thank you for inappropriately deceiving me.
