Pathetic service for a simple request

According to Cell C, it takes 3 working days to upgrade a fibre line from 20mbps to 100mbps, right? Wrong! I requested the upgrade on 31 October and today is 24 November and still no upgraded line. After speaking to multiple people in their C-Fibre support division on a weekly basis, no one can give you a straight answer or take ownership of the query and see it through to resolution. Mind you, they have confirmed that the package has been adjusted, therefore i will be paying for the service THAT I AM NOT RECEIVING! I have sim, data and fibre contracts with them and this is the PATHETIC SERVICE they offer to loyal customers.
