Bad customer service

Saturday the 29th of September I went to makro at Strubben Valley to upgrade my vodacom contract. The consultant told me im not due for an upgrade, I must come on monday the 1st of October because ill be due to upgrade. Then I decided to come on the 2nd since I knew Im due and the deal I want was going to end on the 6th of October. When I arrive there the consult took my id document to do paperwork, when she was about to release the phones the head office told they have stopped the Vodacom deals but when she checks on the system the deal was still valid. She consulted the sales manager and the sales manager told her that thers nothing he can do because its a matter of Vodacom and Makro. Me and my wife insisted to see the manager but he took almost an hour to see us and he didnt even apologize neither to give us a proper reason. He just gsve us the numbers of Makro head office so that we can hear from the head office what is the real reason why they stopped the deal before it ends. I tried to consult head office for several times and phones just rings even now. We felt helpless and angry about the treatment that we got from Mr Naresh Bachoo the sales manager.
