SA EXPRESS AIRLINE : Disappointing Service and no Recourse

I had a terrible experience with SA Express. my friends and i planned a long weekend getaway - and they spoilt every plan we had - we had to miss a day of activities already paid for, we had to cut it short, we had to fly from cities we didnt plan to fly in, we were nervous through out the weekend, especially because we had left the country and were fearful of being stranded in aforeign country. there were cancellations and delays and no one would inform us why. we were runnning around trying to get info. We sent an email complaint to their customer services departments and 3 weeks later and still no response. its terrible, its like they dont actually care that their customers lives have to stop when they mess up and dont do what they should be doing .
