Most pathetic company

I have a 10mg line but only get 1mg. I've phoned Telkom twice and logged a fault (always with high call volumes- even at 10pm). Each time I get a message saying my fault was resolved. I've requested a tecnition twice but still waiting. Its now been 2 months, still paying over R800 per month. Will I be reimbursed for paying for a service that I don't get?
