VERY RUDE ATTENDANT

I flew this afternoon from Antananarivo on SA Airlink 8253 and my sit number 16A. While serving food, the steward informed me they have run out of chicken and suggested beef or samp, I opted for the samp but about 45min later, I got a severe throat irritation. I pressed the attendant button and the lady (none of stewards had a name tag) came and I asked for some water and she said, she is bringing. 12 min later she had nit still brought and i was coughing severely by then, i pressed the attendant button 7 times and none of the two ladies came to me. I walked to the business class and found both ladies serving about 5 business class passengers but the one attendant was so rude to me making it business class is a priority then she will bring water. Her colleague had to ask her to give me water and she did! I am regular on Airlink flights as you would check it but that attitude wasn't necessary and it wonder if I had collapsed, the emergency would have escalated UNNECESSARILY or she would provoke another passenger who would get physical going from a simple case of giving a passenger some water!<br> Please address this with your stewards and give them name tags for identufucation.
