Review of Imperial Nissan Renault (Durban)

I bought a used car on the 28-08-2016 and now i need to do a service and pay for it but i only used that car only for 8000 km, why the service was not done before i even take the car as i was told when phoned for quotation that the service was supposed to be done in may 2016 as it was last done in may 2015. according to the kilometers yes the car is due for a service but on the book it says next visit must be on ******** km or 1 yr.and if i call for quotation I am getting 2 difference quotations, and when i speak to the sales man he is also telling me 2 difference stories he started by asking me send him a proof of a service history after 2 days i send him an sms to find out if he received my email and he said last time we spoke i told you to book a the car to the closest renault dealer and pay for it of which he never say that to me. why did he asked for copy of service history if he said that? i need to know what is the really price for service and why the car was not serviced last year as i was told?
