Disappointing Service

So they sent me an email confirming that i can take my car for service, i do that. Renault sends them the quotation they then refused to authorize stating the meter reading is incorrect, Renault then sends them a quotation with the accurate reading as well as a picture of my odor meter reading and licence disc(MVIA denied receiving that email). I had to have a back and forth conversation with them for 4 hours straight, The agents deny receiving pictures of my odor meter, i had to inform them i have been copied in each communication with them as they are *********** and denying receiving information regarding my service. As of now Renault is keeping car because no payment was received or approval from you guys on top of that i have to deal with RUDE agents with the caller ID ***4. I DO NOT HAVE A CAR and 7 months pregnant with twins wondering how will i get home because of your incompetence. They do not deserve that one star
