Poor poor service

On the 13/042016 I went to MTN Bay west mall to do a sim swop. At first I went to the shop on the second floor. When I came there they told me they wont be able to help me with a sim swop because they had stock take the previous night and still need to sort out some stuff. I went downstairs to the other shop. I spoke to a guy and he went to the back for a few minutes and said that the computers was offline. These shops hardly work during the week because of the low traffic during the week and each shop sends me away. I went back to the first shop and the lady tried to explain to me after I said and will report this. Stock take should be done after hours and be sorted before the opening of the shop. Really really bad
