Terrible service from Cell C fibre support

Ever since I took a Cell C fibre contract I have been struggling with slow internet connection. It has been 10 days now without connection and no one from Cell C is interested on solving my problem, I have to buy data but I am paying for fibre. Everytime I call I am told the issue is escalated but I don't get any feedback to date. I tried to contact Cell C fibre support on their Twitter account still no help. Ref CF164130
