Telkom lies

I upgraded my telkom mobile contract with one of the black Friday specials, and noted that I did not receive the free data (which was the sole reason for choosing the package) as specified. I called 180 last Saturday, and was told to go to the store. Went to the store on Sunday, and was told to call 180. None of the customer care personally logged an incident as their system was either upgrading on Sunday, down on Monday and Tuesday, or they simply blamed the store. Drove back to the store on Wed, where the lady called 180 and an incident was logged, and I was assured of a 72hr TAT. Come Sat, still no data was credited, and the call center was not helpful...drove back to the store and they logged yet another incident and escalated the prev one......I have had to buy data and will not be refunded by Telkom...Took their phone back in the afternoon and requested a contract cancellation and was told that was not possible. Gave the phone back anyway, as I was sold a LIE. No apology, no compensation, just endless unkept promises. Such terrible service!!!!!!!
