Internet speed close to zero paying for a 10mg lin

I am so frustrated, I have logged countless faults and phoned countless times, yet my Telkom Internet sevice and speed is pathetic. I am paying for a 10meg line yet my speed sometimes reads 0.04 which is ridiculous. I pay almost R1000 monthly for this pathetic service. My telkom phone line cuts off and is super noisy yet the call centre told me there is no fault on the line . I tried to downgrade my line & was cut off while speaking to the call cente.
