Worst service ever

I went to Telkom shop at The Glen to purchase the Smartbroadband wireless 5GB service. When I got home the sim card said "not activated on network". I phoned 180 and was told to wait 24h. When it still did not work on Monday, I phoned 180 again and was told to phone 10213. After spending 3hours (5 calls) on the phone, I was told they cant help me, I must go back to the shop. I went back and was told it showed as cancelled, they do not know what happened and they will phone me when it is fixed. The following day I was told to come collect the sim, it was activated. When I got to the shop, they did not know what I was talking about and I had to wait another 45min for new sim card, which I was told was definitely working this time. Last night when I wanted to use my night time surfer data it showed I had none. I phoned this morning and was told it is not the Smarbroadband wireless package that was loaded on the sim. The page I received from the shop clearly shows "SmartBroadBand wireless 5GB". The lady (180) told that I had to go back to the shop. This is seriously unacceptable. I already had to take of work twice to try and sort this out and spend hours in the que at the shop. I want this fixed!!! I signed for SmartBroadBank and that is what I want and I AM NOT GOING BACK TO THE SHOP. Telkom made the mistake, so you fix it.
