eDreams complaint: Cancellation of Flight

My connecting flight to Lyons on Saturday 9 July. was cancelled. I had the app and it clearly said that in the event of cancellation they would resolve within 2448 hours. 24 hours later I made the first call. I was assured that they would fix it and that they would elevate the modification to the team. I would hear in a matter of hours. Nothing happened. I called again the next day but after an hour waiting, I decided to use their chat feature. The helpful robot kept telling me that there was no problem. The app information made it clear that it was. After several insertions of the word wrong, I was transferred to an agent. This agent told me that it was good news and that the matter had been resolved . All I had to do was wait 6 hours and I would get an email with the new flight details. This is the day before I was due to fly. No email so I went through the procedure again and was told that the request was being dealt with and they would solve it but I would have to wait 7 hours. Half an hour later I received an email saying that they couldn’t do anything and that I should contact the airline directly. Of course there was no option to reply to them.
