Terrible service, very inconvience, not to be trusted

Rented car from 9/12/2022 to 9/01/2023 from Oliver Tambo. The WORST company I’ve ever rented with, first and last time. Booked my car online for R10200+ . On picking car in O Tambo the money has been increased to R17000+. Extras that I have rejected during online booking have now been added, rate of rental per day has been increased, Excess kilometre rate has been increase from R4.50 to R5.00. I gave copy of my fully paid booking to the lady on desk , she made phone calls, gave me no feedback. On arriving home I got email with outstanding balance of R7000+ despite having paid the booking in full .My fully paid online quotation completely ignored. On Monday I had to drive back to O Tambo from Newcastle to dispute this as I have had no response from the email I sent as well as the WhatsApp I sent to MD as pers invitation message to contact him on his personal number if I was unhappy with service. Then this inconvenience journey clocked unnecessary excess kilometers.Such an inconvinience caused for my time and financilly. Returning the car on Jan 9th 2923 , anything I owed is added on the bill I have already paid, which increased VAT, levy, airport tax. Passing through toll gates, I paid in cash two of my journeys as the car tag did not clock. When I got bill for toll gates and etolls, I was again charged by Woodford for toll gate fares I have already paid. I sent email to advise them of this, they ignored my email and continued to charge me. I felt I was being deliberately ****med! I have never experienced such a terrible service through the years of hiring from O Tambo. Even if Woodford was the last company left on earth , I would rather cycle for days than using their service.
