Pathetic upfront service!

Shocking. There's no other word that fits more perfectly with the lack of service from CellC. They're apparently a business facing collapse. Yet when somebody, such as myself, looks to upgrade their current fibre service with them, they don't even have the professionalism to keep in contact. No wonder they're facing collapse.

I logged a call on Sunday 18 Aug to upgrade my current fibre connection from 20Mbps to 50Mbps on the Connector package which includes 2 sim cards. They never responded on Monday, so I called. Then I received emails on Tuesday which I responded to asap on Tuesday. On Thursday, I still hadn't heard anything, so I sent a follow up email. Today, Friday 23 Aug, I still haven't heard anything so I called them.

Upon calling them, I find out that there's something I need to do on my side. So why didn't they call me or email me to inform me of this??? Why must I waste my time and efforts to call them? Is it too much effort for them to type a quick email? If this is the level of service, then I may as well change service providers entirely.
