Bad service incopetent and rude staff.

On 23 Dec 2014 I took my Tempo watch that was under guarantee in to get fixed as the pointers were loose. I got told that if there will be any charges they will call me for authorization. My slip said the return date was 22/01/2015 on the 16/02/2015 i decided to call as I haven't heard anything and I was wondering why it took so long. When I called my watch suddenly was just delivered on the same day. I went to pick it up on 17/02/2015 . Suddenly shee charged me R25 Rand. The person who helped me could not tell me why there was a charge and said she cant give me the watch without payment. Surely I should know what I am paying for. I did not bring cash and was not informed of the charge, i said I will pay on my account. She said it is fine until she rang it up as cash and then insisted on cash as she could not authorize the system. I told her that I feel there is incompetency all round and I will contact Head office. After which she started shouting at me that she will contact them for me. I walked out the store with her still shouting as I exited. This is not my first bad experience at this store. They waste my time. Charge me extra with no explanation and I get shouted at. its BAD
