I was ****med out of my flight by requesting a flight change!

I called in to Lastminute.com customer service line - *** on Wednesday afternoon -16 December 2020 - 72 hours before my flight which was to request a flight change.

I was told that everything has been approved and I need to wait for an email to confirm my change request. I hear nothing and call back the next afternoon - 17 December 2020 for a follow up. Once again I was told not to worry an email will be sent to me shortly.

I then received an email less than 24 hours before my flight stating Lastminute.com want to disucss my flight chnage. When I call back I am then told because it is less than 24 hours before my flight last minute.com can no longer change my flight and I have to speak with Lufthansa Airline directly. I call Lufthansa and they tell me there is no such policy which states this and because I booked through Lastminute.com they are unable to help me. I went back and forth numerous times and got the exact same answer every time! I have voice recordings of a customer service agent from Lufthansa stating that there is no policy which says that 24 hours before the flight the customer must contact the airline directly for a flight change and that Lastminute.com are lying! My flight has now left and I have lost an £850 flight! I even bought a "Flexi ticket" to avoid this kind of situation!

They have no customer service email adress either so there is nobody to compalin to!
