Unsatisfied and unhappy

We are due for an upgrade which any person would be excited about, however now not so much.<br> Our upgrade date has been confirmed by the call centre for the 09/02/2016 as well as the USSD code.<br> We went in store to Lakeside mall on Sunday the 7th of February ad we were told we are not able to upgrade 2 days before the time which we excepted, however we took a chance as it was weekend. We were then informed by the consultant that we can only upgrade on Wednesday the 10/02/2015 as the it has to be a day after the due date. From Monday I have tried numerous times to contact numerous branches to enquire about stock, however out of the 5 branches I contacted no one answered. Tried the call centre and they were unable to assist me. So we went in on Wednesday to do the upgrade, we were assisted by a consultant who informed as she has resigned. First of all no stock nor in the warehouse, no branch has besides Fourways which they were unable to get hold of because no one answers phones as we were told by the consultant directly. Due to her resignation she was not at all interested to help and advised that we have to wait another day for the upgrade! I feel like cancelling!!!!!
