Contract Issues

I went to the gym like always but forgot my tag. When my sister brought it and I swiped in I saw that my details were wrong. My sister said that this happened to her as well(The same information displayed) and I thought I'd quickly get it sorted out and start working out. This was not what happened. My information was not found on the system, and it showed that my contract expired, like it did the previous time before I got a new contract. I argued that I always pay my full subscription upfront and that the system is wrong, but I didn't have my contract anymore so I let it go and took out a new contract, I don't mind the money and I like working out. <br> <br> My complaint is about the way the situation was handled by the manager. During all of the talking, I was accused of *****ing the tag multiple times, although I told him I won't mind taking out another contract even if my misplaced contract only expires in March'2016. My tag was thrown against my chest by the manager when I got a bit frustrated and my tag fell of the table after I lightly flicked it onto the table(I have a witness, I did not lose my temper or use any force in any of my actions). <br> <br> So not the contract, the situation.
