Discovery Vitality Travel

Absolutely no help at all. I lodged a complaint *** 10 March 2022, which has been escalated, but to date, not resolved. I had booked a BA flight to the UK for June 2020 which was cancelled due to Covid by BA. I received an mail from BA giving me the option of either getting my money back (R9117.33) or a voucher, Stupidly, idiotically, I chose a voucher. BA then sent me an email giving me a voucher number (***). In February 2022, I felt safe enough to rebook my UK flight. However, on the site, my voucher was "invalid". I contacted BA who redirected me to my travel agent or booking agent Discovery Vitality Travel.... they have not helped either. this is STILL not resolved. Friday 8 April, I receive a telephone call from a lady called Shavvon who thought that the dispute was settled. It is not. I have not received a new valid voucher number, nor my money back. I want to book a new flight and use a valid voucher to get my money back. Whats going on? This is URGENT as I need to apply for a visa, and want to go back to the UK for family affairs. Over a month, and nothing.. If it was not for the good discount offered throught Discovery Vitality Travel, I, now impoverished!!! Iwould book my next flight elswhere.
