Bad quality of service and bad products

I was advised by MWEB to move my TELKOM line to them for management as they would be able to do it better. I have moved and upgraded my 1Mbps line to a 4Mbps line and changed the management from TELKOM to MWEB at my cost. I have now since November last year had continues disconnects on my line terrible latencies and can even watch Netflix at night (and I am not downloading anything at the time I watch Netflix) I am now going in the 4th Month with this bad service. I have now decided to move to another ISP, but it took me a month for MWEB to send me the cancellation info. now in the new month I have to still sit until end of March with their horrible service as I have to give a months notice. I have all the emails between them and me and proof that I had to follow-up on my own call. They did not even have the decency to keep me updated on my ticket that I logged with them.
