Worst service ever

WORST EXPERIENCE EVER!! AVIS KINGSHAKA

hired a car and on return found that the wheel caps were missing , i asked for them to double check camera footage and had no issue paying for it if it was indeed missing , they advised they would contact me to discuss further however without any communication the took away deposit of R2000 and a further R5000 without advising me at all , didnt even send me a email. i called numerous times with no answer, i eventually got through by calling a customer service helpline who was also unable to help me and advised someone will call me , the person called me and still gave me incorrect information , advised me incorrectly on what was taken from my account , said they would call me back to retify their mistake and return my money but nothing has been done and its not over a week. they dont answer when i call and have no rep**** to my email
