O R Tambo International airport parking

Parking Mangement Office just Rude and dont have any way listen to your problem. I went to go pick up Family yesterday at OR Tambo airport .. I then did not see any signs to say where to park so I took Parking Level 2 South went in by the boom gate and relaize I was in the Long stay parking . I park my car and see if there was anyone to assist me to the correct parking .... I could not find anyone. I got in 17.30 ... I then find security ask him he refer me to Level 2 and say must look for parking office so I did after walking around for 20 min I return to my car phone my Aunti and say I dont know where I am I send her in whatsapp then photos where I stand . Then when they found me after walking 15 min threw the airport we went to parking ticket stand to pay the ticket it told us to pay R430 somthing like that then we found another security then told us on Level 1 is the Parking Management office as I left my aunti them at car as my Uncle could not walk anymore I went in lift then go to Level1 where took me another 10 min walk when I got there I explain the lady what happen she told me is my own fault and I need to pay R150 I told her I dont have that money and I park wrong she told me is my own fault and I need to pay that because she doing me favour not to pay the full amount of R400 and something . I then walk back to car to tell my aunti and she went with me to the office they still did not want to believe me . Aunti insist that we then speak to manager. After waiting 10 min he came ask us he understand we got challange. After I again told him the story he straight tell me I was lying he dont believe my story and that there is signs and people to show where I must park . While busy explained to him another passenger came and stand with us and said he paid over R800 for parking for one day ... so my aunti day she will never use O R Tambo again to fly . The manager then start saying because we where complaining we let everyone want to complain also .After we the problem could not be resolved and look as its juat getting worse we decided to pay the R150 and just to avoid further conflict and to go home. This was very disappointing after it really happen by accident I took the wrong turn . My aunti have no intention to fly again from O R Tambo due to this stressfull situation. I have the parking card where time was up also voice recording with the lady and pictures to aunti to show here where I stand when I was lost
