Poor customer service from SAA

On the 1 Feb I've sent an email to SAA to find out whether I am allowed to take a birthday cake/tart onboard. I received an email back from Bhekokuhle Mazibuko saying the following We have taken the liberty of forwarding your mail to our Reservations Department who are best equipped to assist with such enquiries. For ease of your future interactions please take note of the Reservations contact details;|Email – *** or Call (+27) 11 – ***. South African Airways Case Reference Number: *** And that was the last I've heard from them. I phone SAA Monday, 5th Feb and spoke to a lady which I can't remember her name. She was very friendly and helpful and assured me that I can take the cake on board as long as I am not sitting in a seat at the emergency exit. She also confirmed with me that she will get Bhekokuhle Mazibuko to give me a call, but unfortunately I am still waiting for that phone call.
