The worst internet provider

I have experienced slow internet for 2 months straight now. I have proof of my internet speeds in Durban and I spoke to many consultants. I am really fed up with this poor network and I have brought it up straight to customer support which takes days to get back responses. There isn't really any improvement on this network. And I have taken it to report them for being really poor in the telecommunications area. I've even sent them messages on Facebook which would take days to get responded. I can't even play online games due to lag. Please fix your servers. I have had this problem from last year and I cannot deal with this situation anymore.
