Sick and tired

Terrible connectivity, more down time than anything and paying for speed that I am not receiving I was told by the Openserve and Tech Doctor. I am honestly tired of paying almost R1500 monthly yet I am constantly on the phone or email with Cool ideas with no resolution. I have spoke to Alex so many times I've had people come out but the issue has not been solved. This is exhausting and If I cancel my contract I'll be penalised yet I am not receiving the service I committed to or am paying for. What is the way forward because this is ridiculous now?
