Wheel Chair Assistance and bad attitude from Mango Employee

My mun had a flight at 4pm today to Durban. I had caled this morning to make arrangements.for a wheelchair due to my mum not able to walkong distance and the person I spoken to told me to request this at the counter.I get to the check in counter and the lady says no she cannot request a wheel chair as it is very short notice yet I called in the morning to make arrangement. My mum had to walk but I asked a gentleman at Mnago to assist her with her baggage. The lady at the counter says that they only allowed 5 wheel chair passengers per flight. Totally disagree with this and I would suggest you review your policy on wheel chairs.

Attitude with a lady by the name of Lorraine. Unfortunately i will not tolerate disrespect and rudeness from an employee. She has no customer service at all. I would like this to be addressed.
