Vodacom Fibre lies

For about 6 months now i have been calling vodacom fibre customer care about a service request complaining about the the fibre internet line just randomly dropping. They turn around and tell me that its a infrastructure issue but when i check and call the instructor they say they not having any issues. Today alone in the space of 10 minutes my internet has dropped 3 times and i study from home and have to hand assignments online. Is vodacom going to pay me if i fail my co**** cause of there faulty internet and lame excuses i don't think so.
