Telkom Mobile Never ever ever again!

I have a Telkom mobile cell contract. I received an SMS about a month ago that I can upgrade soon. I phoned the call center and the lady told me I can upgrade anytime from the 1st of Sept. On the 1st of Sept I went to Eastgate branch. The lady told me they had no stock of the phone that I wanted to upgrade to. She also informed me that I can only upgrade on the 4 Sept( already different to what the call center told me). She informed me that Alberton branch have the phones in stock and she will ask het manager to fetch them as the manager were not present and the lady did not know when the manager will be available. I followed up the next day and the lady told me she did not had time to speak to the manager and she is not sure if the manager will be able to fetch the phones. After I give up on this branch I went to Greenstone mall Telkom. Also no stock of the phone. After he looked on the system he told me that I can only upgrade on the 5th ( three different dates from three different resources) *** Telkom?? I wasted my time and money for nothing. I understand now why all the Vodashops, CellC and MTN shops are always busy. Because Telkom's customer service SUCK !
