They will find something to make extra bucks and cheat clients

I am awaiting feedback since I lodged a complaint on the 11th of March 2019 regarding the unfair charges on my invoice. I rented the car from 14:45 to 14:45 (24 Hrs) yet I arrived at the till point early to get the rental agreement started on time, we ended up leaving the pick up location after 14:45. The reasons would be delay due to poor communication at the till point and almost being denied the rental with claims from the tempest lady saying my license is less than 3 years old and ofcos many attempts in helping her get the count right. The following day my husband phoned to enquire about the return time since we were running a bit late and needed to wash the car and fill up fuel, of which we were informed we had to return the car at 14:45 but would get an extra hour without being charged. We managed to take the car back at 15:40, but my invoice comes back with 2 days extra charges. Time on the invoice recorded as 14:23-15:42, very shocking and we have been cheated. I made calls and now 2 weeks later nothing has been said as feedback!
