HORRIBLE SERVICE I'M GETTING FROM SELECT CAR AND VANRENTAL

I've rented a car for 3 days with Select when i went to Durban for a holiday, i got the car on the 10th April 2018 and returned it on the 13th April 2018. I had to pay a refundable deposit of R5000 which i was told that it will be refunded within 7 working days. I returned the car on the 13th of April with no damages and petrol was full. After 7 working days i asked why the deposit is not yet into my account? "Shabir" the guy who was assisting me said it's actually 14 working days and not 7. This i was okay with, after 14 days i called them and asked why the money is still not in the account, i was told that the payment was affected by the holidays (27 April and the 1st May) and i was told that the money will be in my account on Friday (04th May) latest Monday (07 May). On Tuesday (08 May) i called them and this time i spoke to a lady by the name of Rose in the morning and the moment i mentioned that I'm calling regarding my refund, she said she'll call me back after 20 minutes "She didn't have my numbers though". I kept calling the whole day of the 08th May getting the same message from both Rose and Shabir that they'll call me back abut they never did. The next day (09 May) i called again and spoke to a lady by the name of Jacky who said she's aware of my query and the lady (Head Office) that was dealing with the query was on leave and only returned on the week of the 08th May, i asked for that lady's number and name (Lizzy). On Friday (11 May) i called Lizzy and asked her about the query and she mentioned that the money will definitely be deposited in my account before Close of Business Friday (11 May), i waited for a notification the whole of Friday but there was none. Okay, i decided to wait for the morning of Monday whereby no notification came. I called Lizzy again and she then changed the story and said she was waiting for the Chief Financial Officer to approve the payment while on Friday she promised that the payment will definitely be in my account and before we finished the conversation she hanged up the phone on me.

Select Car And Van Rental's service to me has been horrible, i'm shocked that what they requested on the 10th when i hired the vehicle i gave them without any hustles but now when they have to return what belongs to me they are being this unfair. TILL TODAY MY PAYMENT IS NOT YET IN MY ACCOUNT AND IT'S 30 DAYS PAST NOW.
