Arrogant and Disrespectful Manager

my mother came to the breakers resort front desk to complain that at 8am there were no umbrellas or chairs available at the pool deck,the manager EDWARD PILLAY thought she and her complaint was ridiculous and found it appropriate to laugh in her face and say that she didn't get to the pool area in time and that they had enough equipment for all clients,although we weren't the only ones complaining.He continued to smile as my mom complained in her anger and to no avail this unprofessional individual continued to state that she was too late although throughout the day so many went without the said equipment which i later found out that many chairs and umbrellas broke the day before due to the weather which I'm sure he Had knowledge about.instead of apologising for the situation and saying that he would try to accommodate my mothers needs he found it appropriate to argue,deny,laugh,smile and be disrespectful and unprofessional.when i decided to approach him and his unprofessional-ism and his disrespect towards a client and a woman he once again decided to smile incessantly while i raged as in my culture it is one of the most disrespectful,low class things to laugh in someones face.
