Apathetic customer service!

Having booked a flight pre-lock down, I have been trying for 5 weeks now to get a refund. I qualify age wise and I have been given the runaround. Whilst the refund officer Andile Dunga is very pleasant, he keeps repeating himself that it takes 7 to 14 working days. They have already tried to fob me off with a voucher. I cannot believe that so many customers are applying for refunds as you have to be over 65 to qualify. In a stressful time for all of us, they could have generated much goodwill and increased customer loyalty. I have flown with Mango for years and it is sad that existing customers can be treated with such disdain.
