Useless and ******** vodacom Fibre

I'm very ****ed with vodacom Fibre. I'm subscribed to a 10mbps line but I get 3mbps speed. The line is always down and slow but they have a nerve to even debited me double the monthly premium for the useless line. I have never have joy with vodacom Fibre. No one is willing to help. Even the c.e.o office just promised to help but zero help so far. I want my money reversed and line fixed... I have tried to cancel twice but they close my cancelation ticket without canceling or even calling me... Vodacom Fibre is a bunch of ****** and useless service.. Packaged in one.
