Upgrade Hassles

I'm a WebAfrica customer. I have fibre internet at home and I want to upgrade to a faster service. The only way to talk to WebAfrica to do this is via WhatsApp. (There seems to be no way to talk to them on the phone.) So far I've chatted with six different agents on WhatsApp. Each agent asks a bunch of questions, then transfers me to another agent. At which point we start again from scratch with the same questions. Not one of these six agents was able to offer any help.

In fairness to WebAfrica: I've been a customer for about three or four years and their service has been just fine. Its only now that I'm feeling annoyed with them.

It seems that the simplest way to upgrade my fibre service will be to cancel with WebAfrica and then sign up with someone else instead.
