Vodacom Fibre after sales service disappointment.

Vodacom Fibre after sales service has got to be the worst I've ever encountered. They do not have the customer's interest at heart. How do you allow a paying customer to go a week or more let alone a single without the promised service. They provide no feedback, they promise to call you back with updates but they never do. I have to call them every single day and sometimes stay on the line for over an hour while they go through the same details over and over. Why can't they sort out issues within a day. Why does it take a week or more to fixed what I consider a simple connectivity problem.
