FLIGHT CANCEL IN CANCUN-WHAT TO EXPECT

our departure was 1:45 pm and actual time was 2:45 on a saturday. We were aborted on take off and had to deplane for aircraft problem. We were not told that the flight had been cancelled until 6:45. Also, we found out the flight crew had run out of flight time at 5:30 that day. We were not returning to dallas this day. We were not informed of any of this. No representive all this time was ever available to ask questions about what was happening until about 7:30 that day. Sun country then gave us a $25 voucher for each person for dinner whlie they made arrangement for the night. The $25 voucher sucks because the cancun airport is very exspensive, two pieces of pizza was $21. They finally found hotels for about two hundred people (that is a guess) about 11:30. We had to retrieve our luggage and board the buses. After arrival and check in we were in bed about 12:45am sunday. We left the hotel at 7:30 am sunady. It took over two hours and a half hours to check back in and to go through customs. Sunday is the most busy day of the week in cancun. Then we found out our crew left on a esrlier flight back to their home base. Sun country had to fly in a new crew. We were supposted to leave at 11:10 sunday morning. We did not leave for dallas until 2:45 pm.
my question is, why we were not informed of what was happening all those hours and they should have been working on hotels beginning at 5:30. This is the identical thing that has happened to us for third time flying sun country. Each time sun country said they would improve. Did not happen.
