Inconviency cause by airline - British Aiways - Comair

Incovienced by British Aiways and doesnt even bother about passanger welfare what so ever. Im still incovienced left with no alternative. I bought a return ticket from Or Tambo to East London for the 02June 2022- returning on the 5th June 2022. Now yesterday morning i receive a call an agent from Computicket informing me that the flight for the 2nd morning 7h00 has been cancelled its either i refunded my money or book another flight ,this doesnt end there, the return of 9h00 flight from East London to OR Tambo has been callenced too to 18h00. I asked for a refund so that i will be able to book another one O2 / 06/ 2022, she said unfortunately the refund will be paid after 6/ 8 weeks , and i have add additional ampunt R200 bare in mind its not my fault the flight had been cancelled and i have cover the amount of the flight if she has to book. The whole inconviencing issue is im being violeted of the right to be compasated for the whole shenanegan. Its worse m travelling with my husband at the same time but but different airline , we booked a car to travel from East London King William's he wont be able to drive on his own becuase of ill health and i have meeting to attend on Sunday at 16h00, prepare for catering for the meeting as i new that i would in Joburg by 10h30 Sunday the 5th. Its on the 02 June 2022, i have to drive to deserted area from East London to Debe Nek beyond King William's Town full of stray animal as this is a rural area. I would be happy if i could get assistance to resolve this from Hellopeter.Please...please...
