Poor service from fibre department

I have been having problems with my vodacom fibre for a while now. I have to reset my router almost daily. I have phoned their technical department a couple of times where they would do stuff and fix my line speed for a short while. Tonight I phoned the technical department as my line speed is only running at 80 meg download and I think I have a 300 meg line. The consultant was of no help telling me she will send me a email and I must send a screenshot of my line speed to vodacom. There was no effort from her side. I have alot of contracts with vodacom and are happy with them but not the fibre. I am at the point where I am thinking of canceling my line with vodacom.
