Green Motion and Kenings should please refund my deposit

1. I booked online to hire a car from Green Motion in Cape Town. It turned out I would be hiring from Kenings Car Van and Truck Hire. When I received my invoice from Kenings, the amount on the invoice was less than the amount deducted from my account. And these two amounts have to be the same in order for me to reclaim the money from the sponsors of my trip. 2. I paid Kenings a deposit which they promised to refund 3-5 days after I return the car. I returned the car on Sunday, 29 May, 2022 and I am yet to receive the deposit. I tried calling several times but the calls are ignored. I won’t advise anyone to rent a car from these two companies.
