After sales service is non-existent

Changed card details which interrupted the normally scheduled payment. I fixed this and settled my balance. Now I've been trying to get my internet service reconnected, but I can not reach Rain at all.

I've tried the support number (left waiting for many minutes multiple times), tried making support queries on the app (nothing), I've contacted the sales agent who assisted me (nothing) and I requested a new sales call to be referred to support (of course they called, but the consulted ended the call after stating that I should call support).

I've done my bit. I've tried to get assistance through multiple avenues, but I just cannot get through to Rain. It's actually shocking how bad the after sales service is. Hello Peter is my last option, I honestly don't know how else to get assistance.
