Horrible service at Game

On the 20th Dec I went to buy some food items at Game. I went to the till at the back, stood there for almost an hour with the intention of paying, but when I got to the till I was chased away by the cashier and her colleague. They told me I must go and pay in the till at the front because they are doing paperwork. I told them I always use that till and I have never had problems before. If the process had changed then why wasnt there someone on the floor directing customers to the correct tills? That colleague who was just standing around why couldn't she screen the queue before I got there? I was not the only one with groceries on that queue, imagine standing for that long only to be told to go join another queue? Why do we have to get such a bad service in the location? You do not care about customers, all you do is just protray bad attitude and give bad service. Im so disgusted. It is not the 1st time this store has disappointed me.
