Why do i even Bother

So 6pm on 6th September i got home to find my internet was a bit Broken , it was extremely slow , i contacted Mweb straight away to reset my port to see if it was that. It wasn't !! So Mweb logged a call for a tech to be dispatched so i can get my line sorted. This was 6th September , Till today i haven't heard why my line is not working proper i have phoned 4-5 times to esculate this problem. i have messages from Mweb to say a tech has been assigned to your Problem. 1st message was 19Sept2017 2nd message was 27Sept2017 3rd message was 09Oct2017 now if a tech has been assigned to my fault why after 42DAYS!!!!! is my line still broken why do i not get any feedback Why am i getting charged for a 2mb line if it is only running on a 0.4mb/s download speed

I am sorry but this is getting out of hand , i am having no luck getting my stuff fixed no one can tell my why my line is running so low speed and the best is the normal Monthly fee is paid but i dont have the internet speed im paying for , we are nearing the 2nd month payment with is nearing do i pay for this service or do i start looking at someone else ???
