Ryanair complaint: Delayed flight, dirty plane, staff attitude and pilot landing

We travelled from alicante to Stansted airport on the 5th returning on the 8th of March. Flight outgoing fr8975 and return fr8382. The plane was delayed for about 1 hour going and 40 minutes coming back. There was nobody to inform us about the delay. On boarding the plane there was litter on the floor. It had not been cleaned. There was no hot food as it had not been topped up. Obviously you wanted a quick turnaround. The staff had no manners and not accommodating. The pilot landing was rough. On the way back it was delayed again, causing me to miss my business meeting, as a result I have lost a very lucrative contract. You may not take complaints seriously as i am just one person, but I am a very very influential person and if i am not financially compensated to a high standard, i will tell all my family and friends not to use your airline. This is a cut throat business and especially now with the corona virus you need to be at the top of your game especially with monarch and fly be going bust. How would the chairman react to missing a very important business financial meeting? The whole structure of your airline from staff to pilot training needs to be addressed. This is not acceptable.
