******* to the smaller man

I have recently hired a vehicle from Hertz rent a car, King Shaka branch, on saturday the 27 of january, I was billed accordingly for my one day hire and left with the vehicle, I later returned the vehicle on monday morning as there was a death in the family and the vehicle was a day late, i then found out that hertz had charged me for the extra day, but also had charged me an overdue fee of R700, additional to what i was supposed to be charged, i was not informed that this would be a consequence of returning the vehicle late, now this company has charged me for using the vehicle for 4days , for a big company like Hertz this R700 might not be alot but for a common middle income earner R700 is our bread and butter , as a loyal customer to Hertz and hiring from them for the past year every month end, I am very disappointed by their customer service, after all that i still called in to get a early refund of whatever was due to me which i was informed was an amount of R228 on the 31-01-2018, until this day i havent recieved this deposit.
