MTN UNCAPPED BUNDLE A RIPPPPP OFF!!!

I buy the MTN uncapped bundle to work at home. I understand the fair usage policy and I am completely ok with that. What I am enraged about is the fact that when your fair usage has been used up, the sms says you will be limited to a max speed of 128 kb. Here is my problem when I am in the fair usage, the internet speed is buzzing which again I understand. then when the sms arrives and I get throttled, you throttle me down to sometimes .05 kb. How is that value for money its not my connection and its not my phone it is you and you are ripping me off!!!!! I and many others with the same problem by the way support your company and you have even increased the price of the uncapped bundle and still your service to us is just a plain *******. You are keen to take our money but when it comes to delivering there is nothing. I can live with 128kb I can even live with 80kb but being throttled down to. o5kb .010 is just not acceptable. I have researched this on the net and many many customers have complained about the same thing nothing has changed and no your technical department is of no help. Please do something about it we are the customers we cannot be ignored or given inferior service!
