Appalling airline service?

I have just returned from a 4 week holiday to the UK on my departure with a well known airline I had a faulty entertainment screen that could NOT be switched off and could not watch or listen to any entertainment throughout the 23.5 hour flight-I was also 2 rows from the rear toilets..At the time the cabin staff got me to complete a form to be forwarded to their head office. I also sent an email which was confirmed and told that I would have a response within 28 days-I sent a follow up email and have still heard nothing. On my return flight once again for the first leg of the flight NO entertainement again-however they did manage to move me to another seat one hour after takeoff for the final leg.
Surely I am entitled to a response and suitable monetary compensation as they did not provide adequate service for the full fare I provided. Can anyone advise how I can go about pursuing this matter further???

Drop it. It happens. You paid them to get you to your destination. Nothing else. That is what they did.

Yeah tell me about it. And I used to think those MATS cattle class flights we hitched in the service was bad.
S***t they looked like the V.I.P. treatment compared to the last flight I took a couple months ago. Not mentioning any names but the company's name started with a "D" .

MATS flight might have been cattle class but way I was squeezed in on last flight I took I'll to classify that as sardine class.
I am driving next time. to heck with what the company says.

You do not pay for entertainment. You pay to go from point A to point B. Period.
You also pre-paid for the food they served you.
But you did not pay for movies and other amenities.
