British airways behaving like looters

I booked flights from JHB to Cape Town and due to the current Covid travel restrictions in and out of Gauteng, I am unable to travel. According to British Airways current refund policy, they are refunding tickets due to the travel restrictions. I phoned BA to seek advice from numerous consultants in order to request the refund and all advised me differently. However, I followed the instructions of the consultant in terms of moving forward with the refund process and at the end I received a voucher which was not what I requested and clearly stated I wanted a refund due to their new policy. I finally managed to get a hold of the supervisor on call and she said it needs to be escalated to the refunds manager. Approximately 6 days and have gone by and no feedback as yet. Everytime I call to speak to the Supervisor she is always busy. Apparently now my matter had to be sent to the head office in the UK. Furthermore, most of the consultants I engaged with at BA are rude and abrupt. Is this the kind of service we pay for??? In my opinion, British airways is behaving just like the looters in SA!
