Unused Valid Ticket

I booked a flight for my family from Joburg to Port Elizabeth for March 23 on board British airway Due to the lockdown,i put a call across and spoke with a lady who assured me that all tickets are on hold and valid for 6 months I asked for a voucher cos another airways gave me a voucher but she said nothing like that but the ticket is valid Last week Thursday, I called BA to reschedule the flight as the airways are now opened and for 45 mins i was on the phone with a customer care Representative who obviously didn’t understand what to do as he claimed he couldn’t find my refrence number initially and kept putting me on hold for long intervals For the whole duration of the call,he could not say anything i understood He kept going on and off I had to book another flight to make the trip on Saturday Right now,I dont know what’s happening regarding my ticket
