Rain internet speed so poor

I am at the stage, where I have given up complaining to Rain, the last time I complained was about 3 or 4 months ago, a very pleasant, wonderful, dedicated woman, Tivisani tried her best to help me with my problem, she tried getting the technical department to contact me, she was the only really helpful person. She really tried helping, with many suggestions, which we tried and told her it wasnt helping, sadly, all she could do was forward the complain to the technical department and nothing came of it. To date, I am still having endless problems with speed I am picking up speeds below 10mbps most of the time, and when and if I do pick speeds higher than 4.0mbps it will be for an hour or two and goes back to below 1.0mbps. I can't use the internet, can't watch anything or my son can't even do his work that he brings home, if he does work, he has to buy airtime so that he can get his work done, what a costly affair. So 4 months later, the problem persist, but I am paying monthly, on time. I just am so fed up, that it is not even worth complaining anymore, as nothing ever gets resolved. They give the same excuses, but can never explain why the speed is so low most of the time. I hope by them reading this review, maybe they will hopefully look into the matter and resolve the issue.
