Cellphone upgrade from hell

I went to the Telkom store (Gateway) on 15th Dec (evening) to upgrade my sons' cell phones, only to be told that the iPhone 6 was not in stock. Really, in the middle of December?<br> Today 16th Dec I called iStore and they informed me that the upgrades could be done with them. I went to iStore in Gateway, second in the queue where there was no actual queuing system to speak of, where it took 40 mins to receive the printed forms to fill out. I had to wait yet another 40 mins for the attendant to take my forms, both times I had to ask for a manger to assist. I was told that once iStore received confirmation from Telkom, the upgrades would be complete. We returned later, only to be told that Telkom had not given iStore the confirmation. I went into the Telkom branch and they advised that they had received no order from istore. I went back to iStore and was told that their system was not communicating with Telkom's. Is this my problem? I called Telkom, no managers were on duty and the consultant advised that upgrades could not be done in this way. REALLY??Nobody could have told me this before I wasted a whole day? Incorrect information from both sides, shocking service. VERY UNHAPPY!
