Worst internet supplier

I am in the unfortunate position of living in a town where fibre is not an option and where the fastest speed they can provide me with is a 4meg line. I have made peace with that and expect the speed to be at the very least above 2.5meg/s. For the last 3 weeks I have been getting speeds of between 0.2meg and 1meg a second. After 5 calls logged with the call-center I have finally received a call from a technician today. He however only tells me that he can not come to help me as it is raining. I have been paying them non stop for a service that I am not getting and it appears they are not even interested in assisting into resolving the issue. Telkom is the only provider in our area and they do not care about small customers. WORST SERVICE EVER.
