Vodacom/ Openserve Fibre

Vodacom Fibre / Openserve. I have been experiencing the worst service from Vodacom!!! My wifi goes off at least one a month for more than 5 days with no technician being sent out. I need to call them daily to find out about the progress of my case( this happens numerous times), and the call center agents just tell me to unplug my router which does not help at all!!! I have asked numerous times to cancel my contract but they are refusing.

I have spent so much airtime and data trying to get this problem fixed! Vodacom wont cancel my contract and they are not willing to fix the wifi problem!!!!
