DISGUSTING SERVICE- NO REFUND POLICY

IN DECEMBER 2000 I BOOKED A TOUR(HIGHLIGHTS OF SICILY)WITH COSTSAVER TOURS FOR AUGUST 2021 FOR 2 PEOPLE AND PAID A DEPOSIT OF R6000. AS A RESULT OF COVIT, I WAS FORCED TO CANCEL THIS TOUR(MONTHS BEFORE DEPARTUREDATE)AND LATER AGAIN FORCED TO CANCEL IN 2022 MONTHS BEFORE.I WAS TOLD THEN THAT MY R6000 WOULD BE SAFE FOR MY NEXT BOOKING IN THE FUTURE.I HAVE NOW HAD ONE HELL OF THE PROBLEM CONCERNING MY NEW BOOKING. FIRSTLY THEY DENIED HAVING RECEIVED THE R6000, THEY DENIED THAT I HAD TRAVEL TWICE WITH THEM BEFORE BUT ONLY ONCE, BUT WHAT MAKES THE DIFFERENCE ANYWAY WHEN ONCE WAS ENOUGH TO QUALIFY FOR THE SECOND TIME TRAVELER AND THIRDLY I WOULD NOT BE GRANTED A REFUND. THET EVEN WANTED ME TO PAY ANOTHER DEPOSIT OF R3000 WHICH I REFUSED SINCE THEY HAVE HAD MY R6000 SINCE 2020.AT THAT STAGE I WAS KEEN TO GO AGAIN AS I THOUGHT MY R6000 WOULD BE SAFE AS A REFUND IF I WAS UNABLE TO GO IN THE FUTURE. AFTER A MONTH OF STRUGGLING WITH THEM TO RECTIFY THE INVOUCE AND ACKNOWLEDGE MY R6000 WHICH THEY REQUESTED ME TO SEND PROOF THEREOF WHICH LUCKYLY I STILL HAD, I AM HAVING A PROBLEM WITH THEM AGAIN TO SIMPLY JUST ADD A TRANSFER ON THE UPDATED INVOICE.....NO NEW INVOICE YET RECEIVED 2 MONTHS LATER... LET THE TRUTH BE TOLD, I REALLY NO LONGER WISH TO GO ON THIS TOUR BUT AM FORCED AS THEY REFUSED TO REFUND ME....I NOW JUST WANT MY MONEY BACK, WHAT HAPPENED TO THE CASH REFUND POLICY, I WAS FORCED TO CANCEL WHICH I DID MONTHS BEFORETHE DEPARTURE DATE - WHY ARE THEY REFUSING TO REFUND ME????
