Poor response from airline to a simple courtesy request

I travelled on a flight recently with this airline and upon us disembarking the flight that landed, I requested for the air hostess to assist me in reaching for my luggage from the overhead compartment. She looked at me and ignored me as she looked forward. Once the passengers had left; the air hostess then asked me to remove my bag. I then advised her that I cannot reach as I am currently pregnant. Her response was then "oh, sorry" and she pulled my bag out. I then sent an email to notify FlySafair of this experience and their response was of a defensive nature, in that I would not be getting preferential treatment as it would be deemed unfair. How is it preferential treatment just to ask for someone to assist you in getting your bag? I had to send them this response and they responded again with, I did not advise the check in clerk that I was pregnant. Again, what does my status have to do with needing someone to help with lowering my bag for me? It's just common courtesy. Basically the airlines response indicated that if I did not advise the clerk at check in that i was pregnant, that they were in their right not to assist me. There are thousands of people flying daily, so many of them ask for help in placing or removing their bags with no issue but in my case, I needed to get consent or approval from them first before being assisted. So ridiculous!
