Slow spreeds for over 3 months

I moved to Mweb at the beginning of March 2015. I moved my line from 2mbs to 4mbs and after sorting that out, I was experiencing extremely slow speeds. I reported the fault to mweb on the 4th of March and After numerous calls to the call center, I still have not recieved a solution to my problem. <br> Mweb has told me that it is telkoms fault, however Telkom keeps closing the ticket before having done anything to rectify the issue. Then I have to re-report the line issue and the whole process starts from the beginning. I can keep carrying on like this as I can't even access my internet banking. <br> <br>
