Bad service and attitude

Upon my return to the airport on the 12th november 2015 at around 17:15, I paid for the parking and could not get the receipt. I called the operator for assistance. The lady who was talking to me seemed to not be interested in what I was asking for, she just told me to go to the gate where I will get that receipt. When I got to the gate I called again, she just told me to insert my card and she hung up, I called again asking her where my receipt is as I need to submit it at work, she just told me to call the number *** if I want a receipt. I called the number but the lady (Teresa) whom I was talking to could not assist me at that time and she asked me to call again later, I could not call later as my phone battery was low and it switched off. I decided to call again the following day, but there was no answer from that number. May I please be assisted with the receipt of the parking payment that I made on the 12 November 2015 at parking level 0. Who employs people with such bad attitude at ACSA? It seems like this is the norm as it looks like there is no consequence management, and employees treat customers with disrepect, what a BAD REPUTATION, for such a big company!
