Telkom Data Wallet : Integrated sim - not working

So, my 4mbs adsl line only syncs at 2.5mbs, I lived with this ... recently it dropped to 0.7mbs ... this is no good, so I discover that telkom offers an integrated sim to your adsl account which works on the 3g network. I think , ok great, let me get this sim and then link, and see if I can get better broadband performance. What an epic fail. On Sunday 03/04/2016 I go pick and the sim at the telkom shop. Get home plug it in, and nothing. Numerous calls etc, I go back to the same shop for them to activate it on Tuesday night 05/04/2016. For the whole week nothing works on the 3g integrated sim. On Saturday 09/04/2016 I go back to shop, after standing in the que to an hour, I get to the front. I tell them the sim does not work. They tell me it does, I say show me. They hand me over to some shop assistant who has no clue. So 1 week later no integrated sim, and still slow adsl. I am currently investigating alternatives and will probably switch to Neotel in the next day or so. No-one in telkom is interested in helping me with my broadband issues. With this level of service and in shop, not knowing how to help customers, Its easy for them to loose customers.
