Nice way to treat a new customer

What a way to treat a new customer. I joined telkom two weeks ago and have been without any Internet for one of them. After logging a ticket I got a reference number and was assured I would be contacted a a technician, been waiting 5 days to be contacted (what a surprise). On top of that my ticket has since been closed with nothing being resolved. Been trying to get in touch with customer care, after being on hold for 30+min multiple times I decided to request a call back, about 30 requests and still waiting.

So my question to telkom is what do I as a paying customer need to do to get my issue resolved?
