Bad service from Vodacom Fibre Internet Provider

I have subscribed to Vodacom for an uncapped 20Mbps download and 5Mbps upload fibre internet service line including an uncapped landline. You bill me almost R1,400 per month for this subscription, yet I don't receive the actual speeds I'm paying for. For the last 4 days my download speeds have been less than 6Mbps and tested randomly throughout the week. I have logged numerous tickets including SR180 ********** 61 through ********** ********** to have this fixed. Phone calls to have this fixed doesn't help cause your staff as well as those in apparent senior positions merely note that it's not their department's responsibility and that they would email the backoffice who should address it within 24hrs. IT'S BEEN 4 FLIPPEN DAYS!!!! Your processes clearly lack customer focus and your staff have a clear attitude that you're a giant and losing a customer isn't a matter they actually care about. They're all just salary drawers, not earners cause they haven't earned the right to be paid for their lack of service. I suppose complaining on here is also just a waste of time. After being a client of Vodacom for probably around 15 years it's sad to say that you're starting to turn into another Telkom who just don't care about client service. All you're interested in is collecting my money at the end of each month.
