Wozani car rental Kempton park

These guys are crooks. I rented a vw minibus from them in early January. After returning the vehicle, they said it would take 14 working days to get my deposit back. It's 4 months later and I still haven't received my money. I emailed them and was told they would forward it to their finance department. No further response and they just ignore my emails since. Do not use them. Kempton park based.
