SHOCKING SERVICE FROM MYTRIP.COM

We booked our holiday flights with Mytrip.com which was quick and easy. Covid threw a spanner in the works, understandably so, but when the airline changed the flight schedule, our connecting flight to our final destination was cancelled and no alternatives were given either by the airline OR mytrip.com I eventually requested a refund shortly after finding out about the flight changes. On the 27th of Oct Mytrip.com responded that they'll contact the airline for a refund. Almost 3 weeks later and no reply yet. We were supposed to leave tomorrow! In the meantime I've tried phoning, no answer and have tried desperately to get in touch with MyTrip.com as well as Emirates. Emirates just refers me back to the agent and they don't respond to emails. I find this service appalling and inexcusable. If this is the kind of service that is being provided, I won't be using or recommending them to any of my friends or family in future.
