Faulty service for 7 weeks- bad service/attitude

I have been having pathetic internet speeds on a 4meg line. Loose internet connection about 6 times a day and not getting the speeds or internet service I should. First month with mweb was great. then suddenly problems.Ive done verything on my side from change rooters to testing the service on 5 [URL Removed] to mweb 7 weeks ago.Every week a different technician phones saying theyll look into it.Nothing happens. Some days especially t night internet just goes down.They keep saying they will see what they can do but every week its a different person calling and I need to explain again.I am IT literate and I am not stupid, its not my Router etc. Ive lodge complaints but without success they just do not care. They refuse to send someone out to my house to come and investigate the problem.Ive lodge a complaint with iCASA.I have asked all family members and work colleges to stop their mweb services.Mweb bills me on time every month but cant produce a proper service and keep giving me excuses.they had me do speed tests on different account tha last 4 weeks and everytime they call back I need to do tests again, no one has offered a solution or help.PATHETIC AND UNACCEPTABLE.
