Sani Car Rentalis the worst customer service ever

NOW SANI CAR RENTAL. Appaling service. I returned a car more than a month ago in perfect condition & have not yet had my deposit back. I have sent several emails but on received a response to one, blaming their 'system' of course. I have used many car rental companies & this is by far the worst. *********, ************* & downright *****. ĎONT USE THEM
