Flight delay and cancellation compensation, KLM/AF ONLY

Hi my family of 4 travelled on 30/3/2014 to Orlando via Atlanta on DL39 flight. We boarded on time but once on the plane were delayed by 67 minutes. The captain advised us that it was due to the airconditioning unit at the rear of the plane not working. They had the part and were going to fix it before we took off.

We missed our connecting flight because of the delay and were unable to get on a standby flight. Delta were very good and put us in a hotel overnight and booked us on an early flight the next morning.

We arrived in Orlando 16 hours late. I wrote to them and they came back to me and said that the delay was due to Airport Security instructions, and therefore we were not able to claim.

I replied to them and explained that we had been told about the broken air conditioning by the captain and that was the reason for our delay.

They wrote back to me and said that they had checked again, and our flight was delayed by 20 mins because of the air conditioning and then the other 47 minutes were Airport Security instructions, therefore we were unable to claim.

I wrote back to them and said that we had already been waiting 20 minutes on the plane when the captain told us about the air conditioning, and then it had to fixed, and anyway if the airconditioning had been ok we probably wouldn't have had the Airport Security instructions anyway.

I have now had another reply from them offering us EMD vouchers. Each of us has been given a voucher number and it says at the bottom that the amount is £100. I'm not sure if it is £25 each or £100 each but it doesn't say 'as a gesture of goodwill' or that they aren't accepting any liability or anything like that. The EMD vouchers are not really any good to us,( it took 3 years to save up to go this time the vouchers are only valid for 12 months!) from what I have read I cannot understand where the £100 has come from but £100 is better than nothing. Are they admitting that they are at fault by offering me this in which case surely I should be entitled to the full £500?
Any advice would be gratefully received, I am not a money grabber but our holiday of a lifetime started off as a bit of a nightmare and it wasn't our fault.
Thanks

Sorry i should have said that we travelled from Heathrow to orlando via Atlanta on Delta flight. Am I still in the wrong bit. Sorry this is my first forum xx

Thanks, but I am really confused now because I initially went through Delta but they transferred me to KLM/AirFrance and all my correspondence has been with and through them?!
