BOOKING MPCMDL

I HAD TO FLY TO PE TODAY WITH BA, ALL FLIGHTS CANCELLED. MONDAY 17 AUG. BA GAVE ME VOUCHER VALID FOR 6 MONTHS. MEANING THAT I CAN STILL USE MY TICKET, BUT PAY A SMALL UPGRADE FEE. I THEREFORE NEVER LEFT CAPE TOWN DUE TO AIRLINES CANCELLING FLIGHTS. BA WAS VERY ACCOMMODATING. I HAD A RETURN FLIGHT BOOKED ON MANGO. REFERENCE MPCMDL.AT CAPE TOWN AIRPORT I WENT TO MANGO AND EXPLAINED MY SITUATION. THEY GAVE ME THE *** NUMBER. I LANDED UP SPEAKING TO CHESLIN LAMONT. I EXPLAINED TO HIM THAT I COULD NOT FLY TO PE, THEREFORE WILL NOT FLY BACK. UNFORTUNATELY I DON'T KNOW WHEN I WILL BE ABLE TO RESCHEDULE.I ASKED IF I COULD BE ISSUED A VOUCHER LIKE BA DID. KNOWING THAT I WILL PAY A UPGRADE FEE. CHESLIN SAID I SHOULD KNOW THE TERMS AND CONDITIONS, HE CAN'T HELP ME, THERE IS NO VALID REASON. HE SAID IF I AM NOT ON THE FLIGHT I WILL LOOSE THE TICKET. AFTER SPENDING A WHOLE DAY AT THE AIRPORT I WAS REALLY HOPING MANGO COULD ASSIST ME LIKE BRITISH AIRWAYS. I DON'T WANT MY MONEY BACK, I DONT HAVE A DATE WHEN I CAN FLY. WHY CAN'T MANGO GIVE ME A VOUCHER TO USE WHEN I CAN?' WHY MUST I NOW LOOSE ALMOST R700 DUE TO UNFORSEEN CIRCUMSTANCES. IF I GET A VOUCHER MANGO DON'T LOOSE OUT?
