AIR MAURITIUS STRANDED ME TWICE, COSTNG ME EXTRA $455

DON'T FLY AIR MAURITIUS! Flying Perth-Mauritius-Johannesburg return, I received text and email on landing in Mauritius notifying me that connecting flight (next day) was delayed from 9:30am to 4pm. Next day, I checked in to the delayed flight as normal online - even paid for seat selection - and received electronic boarding pass. Arrived at airport, queued to drop checked luggage and only to discover my flight had been cancelled (not postponed, completely cancelled). The Air Mauritius help desk directed me to check in at SAA, saying we were all moved to that flight. At the SAA check in counter, I was told flight was full and Air Mauritius had vastly overbook. So Air Mauritius notified passengers of a delay but not cancellation?! I went Back to Air Mauritius help desk where staff had ZERO INFO for stranded passengers: no idea how long we'd be stranded in Mauritius, no accommodation/meal vouchers, no alternate flights other than the full SAA flight. I had urgent business in SA (the whole point of my trip) so I was forced to purchase a one-way air ticket for $380 on Fly Safair to get there. Returned to help desk to tell them what I'd done and was advised to complete a claim form on website, no other instruction/action. I submitted the claim while sitting in departures hall before my Fly Safair flight departed Mauritius... BUT IT GETS WORSE! Unbelievable as it is, a few days later, when I tried to check in for my Air Mauritius flight home to Perth, I was forced to pay $75 to have my ticket reissued because I HADN'T FLOWN ON THE FLIGHT THEY CANCELLED! They would strand me in Johannesburg if I didn't pay this nonsense fee - the ground handler in Johannesburg called the airline management in Air Mauritius in front of me. So, Air Mauritius cancelled Mauritius-Johannesburg flight, left me stranded in Mauritius, and then charged me a ticket reissue fee because I 'broke the route sequence." Advice to other travellers: book Air Mauritius if you enjoy (1) buying extra air tickets when Air Mauritius strands you en route to your destination (2) paying nonsense admin fees to catch flights you've already booked, paid and confirmed (3) having an uphill battle to get refunded. TO DATE: no response to claim submitted, no response to phone calls or emails. After reviewing this airline everywhere I can, I'm reporting them to the ACCC (Australia's competition regulator and national consumer law champion).
