Upgrade of line only to be cut off completely

When Telkom contacted us asking if we wanted to upgrade our line, we agreed. Our internet was then cut off and has not been restored for a week now. Although that is not necessarily a long time, we rely very heavily on the internet for our work. No-one can help despite repeated escalations and phone calls. You can't talk to a technician. You can't even find out when a technician will arrive. It is unacceptable that Telkom be allowed to treat customers in this way. The bottom line is that you can't just cut someone off without warning. If I'd known this would happen, I would have stayed with the original line. Just so frustrating and disappointing. Honestly, these days internet is a basic requirement otherwise you can't expect this country to develop and grow. Sort yourselves out. Lastly, I expect reimbur*****t for all of this. We have spent a fortune in mobile data during this time. **********!!!!!
