Poor internet

I emailed support on Thursday 26/11/2020 and i received a response saying that they will reply within 24 hours. I have the unlimited any time sim that i pay R479 and used 200gb data and now i cant use it any more. Im currently getting 0.2 mbps and this means that we have a fair usage policy that im not aware off. We are told a max speed of 10mpbs and i only get 2.4mbps. If i wanted a 200gb plan i would have moved provider. Please can this be resolved or i can cancel the services and move provider's.
