HERTZ has terrible service

The service i got from hertz is appalling and there is a lot of ****** from some of the staff. When i initial went there for the first time in January i was told to wait outside the office as someone else was being assisted, i did so and immediately when that person was done another couple walked in and they were assisted even though i was waiting in line, the person that assisted me was Pieter. I then asked him how much it would cost me to take the car over a month and he was not aware of the special that was running at the time, i then only ended up taking the car for 7 days. when i returned to extend at the end of January i was then told there is a promotion for a monthly rental at R5999, Pieter was there and admitted that he was not aware of the special. The first month went by then i went back to extend for the second month, when i went in to that off i let them know that the vehicle was close to service, Pieter and Dorothy who is the manager then told they will make arrangements with VW in Klerksdorp so i could take the vehicle in for service in VW Klerksdorp. When the time for the service came the arrangements were made and I took the car to VW Klerksdorp only to be told that the vehicle cant be serviced at Pieter had not sent all the things that had to be done. Pieter then arranged that i get another vehicle delivered to me only for him to charge me for the mistake he had made. at the End of March i went to extend again for the 3rd time, the car was at 13700 and i told them and they said they will make arrangements when the car is close to service. on the 20th April Pieter called me telling me he needs to give me another car i told him i was working in vereening and wont be able to bring back the car he then told me he'll bring the car to me as he was going to be making a delivery in the vanderbijlpark office. when the car was supposed to be brought to me i was told that was no longer possible and i would have to bring the car myself which i was willing because potch is on my way from work. on the 20st April i spoke to Pieter and he asked me to bring the car to the office when i knocked off and i agreed. I knock off at 4:30, Pieter called and i told him i was busy with something but will be leaving the office by 4:45 he said he would wait. when i got to potch i called the office and there was no answer so i check on whatsapp to check Pieter's Number only and when i called him he told me there's no one. 21st i was called by Pieter and i told him i had training and couldnt come to Potch he then gave the phone to Dorothy who is the Manager i tried to explain to her what was going on but she was not willing to listen, she was shouting and wasn't listening to anything that i was saying. she then ended up telling me that the car is 'theirs' and they have a right to cancel the contract and call tracker to locate the vehicle and fetch it them selves which i then agreed to, to avoid any dialogue as i was on duty at the time. Pieter came to collect the car and he was still rude when he came and told the Driver to address me as his not going to listen to stories. They over charge with no invoices given when i requested one i was told id have to wait a week while they request it from their head office but to date i don't know why i paid an extra 3000 in the previous month. again this month I'm told to pay 3000 which i don't know what its for because no invoices are sent before payments. they access our as and when they please without our authorization. Hertz doesn't treat the clients the same there is still a lot or racial issues we see in that office.
