Air hostesses

We flew on flight 191 from Mauritius to Or Thambo international on 15th of April. We had no service at all throughout the entire flight from the three air hostesses that worked the economy class.. We saw them when food got brought out and that was the last time until the landing.... Whilst I am very dissatisfied with the service from these three ladies I need to compliment David Riley for his great assistance. He was what appeared to be allocated to first class seats, he still managed to assist all of us in economy class too. David was like the only staff member on the plane. David went out of his way to assist our one family member that was pregnant on the plane and showed so much respect to her, he also made everything so comfortable for our grandmother who battles to walk.. Thank you very much David you made our flight a memorable one and made us feel welcome. But no thanks to the other three ladies, they were of the least use to us, and seems like our usage of SAA meant nothing to them. I unfortunately do not have their names as I hardly saw them enought to get any names. Thanks again David Riley
