hello....can someone give us some advise please.

due to return to uk on british airways flight ba2166 from tampa 22-10-2005,on boarding aircraft seats found and after 15 mins were told to disembark as air craft was unfitt to fly.fault with no 2 engine.we disembarked and were given voucher for meal and hotel accomidation (some were given phone cards outhers like my party were not).

note pushed under hotel door stateing cheque-in would be open 9am that morning.after breakfast we turned up at cheque in at 9,no one avalible untill gone 10.30.some passengers given option to fly from orlando internatiomal and return with virgin.we were not given that option and were told aircraft comeing from houston flight now 9pm that night..(this now puts it 27 hours delayed) meal tickets given out i purchased a phone card to phone family and get long stay car park amended.

returned to gatwick monday morning.

i have written to British Airways and they have replied with £30.00 travel vouchers of which have expirery date (as did the last lot i had of which were for £180.00 and these had expired).

three of us have had to loose a days leave and i have had extra expense with car park.

my question is what is my right to recoupe my loss,on the way out the aircon packed up and the crew had to open the doors to let air through the cabin and issue cold drinks,captain told us there was a problem with the "donkey unit" but the temp would drop as soon as we were air borne..of which it was. thank you for your help
