Definitely not bang for your buck

So I initially app**** for a Vodacom Fibre line 20mbps/20mbps through Vumatel. At the beginning it was quite consistent but of late my line speeds have been like a yo-yo sometimes only get about 2mbps download speed. I have logged complaints with the Call Centre in the past but nothing was really done to resolve this. Out of desperation I recently chose to upgrade to a 100mbps/100mbps to see if that would resolve the issue. I got a notfication email from Vodacom telling me that my line had been upgraded only to find that now I had no internet at all. After calling their customer care and been given multiple exvuses the final advise was to wait for Tuesday as their second line support does not work Weekends or Public Holidays. Despite this advise this morning my line came back online but surprise surprise still at 20mbps/20mbps. I am now beyond frustrated. Vodacom's Fibe is definately one of the more expensive offerings but I was hoping that for this extra cost the service and stability of their offering would be proffesional. I now found that this is sadly not the case. Will Vodacom refund me for the 4 days I have been sitting without fibre and for the mobile data I have had to buy just to have internet? #Frustrated
