Many promises, still nothing realised

I first got contacted on the 29 Oct concerning taking up Telkom Mobile. I was promised that I was in a LET coverage area (I confirmed this numerous times) and could expect speeds of up to 10Mb/s. I then waited for delivery which was late due to no stock, no-one told me this, I had to query. Eventually it arrived on the 17th November but could not be used because the simcard was not activated - I was told to dial a number that had nothing to do with it. Then on the 18th it was activated and I plugged it in and it worked but I less than 1Mb/s download speed (which is pointless), nowhere near the promised up to 100Mb/s. I was on the phone with technical support for 1.5 hours but still got no improvement. I was then given a reference number ***1 and promised someone would contact me within 72 hours. Someone contacted me on the 26 November to get me address and this was the last time I heard from Telkom. I have written emails, I have contacted @Telkom numerous times who have promised to come back to me, but alas nothing. So now I have had a product for almost a month that I cannot use as it is slower than my current ADSL. Someone surely must care, please, anyone?
