Months of pathetic internet speed

I have had the vodacom home internet LTE contract. I have been continously called in and complained to customer service for the last couple of months that my internet speed is extremely poor, when i say poor i mean pathetic, getting speeds of 1.34 and 1.75 mbps, this is pathetic and no one can assist, all they say is its sent to *** and then there is a message on their system that its resolved but no one calls back. YET the speeds stay so low. I feel vodacom has breached contract because they cant offer me a service. If it was 15 to 20% latency i would understand but not 90% plus.

I feel because vodacom cant give me a proper service THAT j pay every month contract should be cancelled and all fees waivered. I expect this to be resolved ASAP. If i dont pay vodacom they suspend my account but if they cant give me a servi e they still expect payment.
