Telkom Maponya, incorrect Contract received

Telkoms service continues to be pathetic over and over, My partner went to Telkom Maponya during the April special for 10Gigs. She was told that they are out of stock and will call her as soon as they have the mifi routers in stock, that took over 3weeks for the stock to arrive with constant visits to the shop and sone of the tellers where rude especially after they opened the store. Eventually She got the router, but when i check the deal its not the one that she app**** for, so instead of the 10Gigs now its 500mb for the initial peice we saw the 10gigs special with. Either the lady who captured the info is *********** or the system. She wanted a 10Gigs "April" promo its not our problem that the store did not have stock, why run a promo and not keep count of your inventory? Someone needs to sort this out because we wont pay for something this ridiculous.
