Poor wifi speeds

Looks like im adding to the 101 thousand negative reviews. There is only one internet service provider worse than vodacom and that is clear access. In regards to the absolutely abysmal service from vodacom , we are paying for a 50mb up and down line from vodacom yet i have been waiting for approximately 2 years to receive that speed. The only thing we have received from them are empty promises and when they do decide to fix it , it goes back to 1mb download speed within the same day. I am positive i would receive beter wifi speeds if i stood on a hill holding a makeshift antenna. I definitely do not recommend their services
