Poor customer service - Call Center

Booked a flight to Cape Town and the system issued my ticket as paid but the payment wasn't finalised on my side. The money has also not gone off my bank account. I phoned customer care yesterday and they promised to send me details of how to deposit the funds which never happened. Called Customer Service again today, held for 10 minutes while listening to the staff chat in the background and then the consultant just put the phone down and killed the call. Has phoned back and still waiting for assistance. I also never received a refund or credit for a ticket when the flights were cancelled during Covid.
