Telkom you are useless

I have had faults on my line since May. The two reference numbers I have been given are: 1221CRK040915 from May and from September 959CRK220915. For both I simply received a message saying the problem is resolved but I believe you have simply done nothing and hoped me being ignored for a few months would make the problem disappear. The line drops and when its working it downloads at a 1/2 mps speed whilst I am on a 4m line. Please can you explain your incompetence, how you can say you are the best value for money network when I am paying for a uncapped line, receiving limited speed, the actual line that doesn't drop and such a poor overall service or actual lack therof
