Dir Sir or Madam,
I Booked from your company a flight for 2 people from Toulouse to Montreal for a total amount of 1152,14€ with details below :
Booking ID 104004648
Toulouse - Brussels, 2020-05-30 06:40:00, 2 pax
Brussels - Montreal, 2020-05-30 10:15:00, 2 pax
Montreal - Toulouse, 2020-06-13 19:20:00, 2 pax
All of these flifgts have been cancelled due to COVID-19 pandemic. I formally requested a full refund through your website (« remboursement assisté ») on the 16/04/2020. We have been waiting since then (1 year and 5 month) and we recieved absolutely nothing so far.
I remind you the european law CE n° 261/2004 you have to refund these as the cancellation is not due to our (customer) request.
With no answer from you in the next 15 days, I will have to escalate our request to our lawyer and to the DGAC in order to get this refund.
Best regards.
