Late notice and inspection at end of contract

I purchased a Mercedes Benz C 200 on 20 September 2014. I took the vehicle on a 3 year Agility package. Which meant that at the end of 3 years I had 3 options - To refinance the vehicle - To take the vehicle back to Mercedes-Benz - To purchase another vehicle I was notified by DEKRA on the 10th of October 2017 that I needed to book the car for inspection. They said that the car must be back at Mercedes on the 1st of November 2017 as my contract is ending on 31st October 2017. The car was booked for a service and inspection by DEKRA on the 19th of October. DEKRA did not send me the inspection report until I asked Katlego (sales rep at Mercedes Menlyn) to forward it to me on friday 27th October. My complaint with Mercedes-Benz Finacial Department is that - I did not get enough notice regarding my end of Agility contract - I have only one working day to repair the car according to the report from DEKRA, because I only received the report this morning - Mercedes-Benz Finacial Department informed me that I will be charged a daily usage rate for any days after the 1st of November if the vehicle is not back with them. - I asked for assistance as it was not my fault that DEKRA did not inform me and did not send the inspection report in time. Mercedes-Benz said that there is nothing they can do about it and they will still charge me the daily usage rate. I fail to understand why I am penalised for DEKRAs delay?? I have called Mercedes-Benz Finacial Department on numerous occasions since last week but no one came back to me, I spoke to Natasha on Wednesday, and then a different Natasha on Thursday who also promised to get back to me. - The delay by DEKRA has caused a possibility that I am going to incur costs that could have been avoided ( my dent and scratch insurance policy expired on 20th October 2017, my insurance does not cover these scratch repairs and the cost of paying the daily usage rate ) I believe that it is not fair for me to be held responsible for these delays. I need any assistance please. Regards Dr Kwena Khoele ********** ********** ********** 512002 (husband)
