ADSL LINE PAYING FOR 10MEG GETTING 3MEG

We pay for a 10meg ADSL line so for the past 3 months we had limited use so we contacted telkom they inspected the problem. They reported back that a earth cable was causing the trouble. "This was supposedly fixed" How ever out of 10 meg we could still manage to get only 2 or 3 meg depending on the time of day. We again reported it. This time they said that it was our router. So we ordered a new Router. New router installed we had just about 2 meg use. Contacting Telkom again the technician informed me that my router was faulty. I tried to explain to the gentleman that its a new router that i opend about 2 days ago. Technician guy said no its my router. Contacted telkom explained they said no cant be router its the wires. Well needless to say Telkom have no customer service we had a problem for about 3 months we have been paying every month we contacted them and asked for a refund as we did not have the proper use of what we are paying for 3 months limited internet use and a whopping R 100 credit. REALLY???? We contacted Telkom today the Response we got is we need to go to telkom's office. Telkom's closest office is +-300 km from us. Really poor service i will not recommend telkom to anyone.
