Mytrip.com complaint: Lack of response

I have booked for myself and my family (2 adults2 kids) flights:
from Geneva (Switzerland) to Beirut (Lebanon), from April 12th till April 24th 2020 via mytrip.com
Booking L2ENOH

Due to the COVID crisis, I have received from the carrier an information that my trip got cancelled.

I have contacted the airline (MEA) and they have ed that from their perspective the trip is fully refundable. But, I need to solve this point with mytrip.com as a booking agency.

I have been writing and requesting professional support since the date of cancellation (for more than a year!!!!). I did contact etravelimytrip.com several times and was expecting a serious and customer-centered follow-up. Unfortunately, no actions was taken besides sending me automatic replies.

Today, July 2nd 2021, more than one year following the cancellation, I have no information on the status of my request, I have no voucher, no refund… absolutely nothing!
