British Airways worst customer service !!!

Worst customer service ever. We bought return tickets from Durban to Port Elizabeth in 30th November 2020. We were informed on the 5th of March 2021 that they are cancelling our tickets , which we due to depart 30th April 2021, they cannot reshuffle our flights to their affiliate partners therefore they will refund us. We had to constantly contact customer supposed via Twitter because their normal customer service line doesn’t get answered. We spoke to Kelly who facilitated the first refund and thereafter we still haven’t received any help , than we were attended by Kev whom was completely useless!!! ,tickets from Durban to PE are extremely expensive and to be told that no time frame can be given for the 2nd refund is absolutely ridiculous!!!! When we went to the customer service at the king Shaka international airport and was attended to by Salina, it appears that , there are tickets on the 4th May 2021 but since a “refund” is initiated, we cannot do the booking!!! To me, this shows the utter disregard British Airways has towards their customers, there is no uniformity amongst their staff! This is not acceptable.
