Ryanair complaint: Not Able to Change Flights

We have been trying to change our flights to next year 2022 for over 6 weeks and are unable to do so! The system is very poor and does not allow us to change flight dates! We have been trying to contact Ryan Air on the telephone and no where on the website does it show an email address!
We stand to loose over £1200 because of the disgusting customer service or lack of it!!!
We had to change our flights last year because of the uncertain situation over COVID and again we are still uneasy over the situation and are forced to change to next year! Although we are now unable to do so.

As we are due to fly out on the 4th of August and cannot speak or contact anyone we will lose everything.

They are the worst airline that i have ever dealt with and will not be flying with them again and will be making sure i let every one on social media know about how bad they are.
