High level of incompetence

The worst service ever experienced with Avis rental.I returned the car in April but i just paid for the damages in June because there was a lot of wrong information on the invoice.To top it up i am always calling to ask for updates as if they owe me but is the other way round. 1. I got charged for an extra day which was not true. 2. I paid deposit of R2500.00 but on the invoice it was noted as R2000.00 and when i query this,the consultants kept asking me for proof but why do i present them with proof when R2500.00 is their requirement for cash deposits when they give you a car,i mean this is not even questionable. 3.All this queries made me curious to go check my previous 2019 invoice, only to find the same mistakes,i got charged a day extra but i was not aware. i would advice everyone to double check their invoices before making any payments because this shows high level of incompetence and *****ulent activities.I am totally disappointed i do not want to lie.
