Word service , no help given.

Worst service i got i a long time. Last year my vehicle went in for a service , were they threw away my service book along with the rest of my cars books. I phoned in multiple times where i was told i will get a call back which i never received. I had to go to the workshop manager because the reception could not help me. After a couple of months i got a service book with a print out paper of my service history.Fast forward to 2023 my vehicles battery run out which made my radio ask for its radio code which i can not get because Star nissan threw away all my books for my car were the radio code is in , phoned in and told the reception lady im not gonna pay to get my code for my radio as it is Star nissan that threw away my book to begin with. On call recording she said I can bring in my car they will sort it out free of charge. On 28th Feb 2023 my vehicle is in for service , were we asked at reception to please sort out my radio with the service that of which we talked about on phone call. I picked up my car today 1 March 2023 my radio is not working any more where the 4 red 0’s were is not showing anymore. I took my car back and they said we never asked them to check my radio , the receptionist never made a note. They say my radio is faulty , which i bought from them there was never a problem on my radio since the battery ran off. I will have to pay to get my radio working again. Worst service and very bad attitude from the reception lady. Will net be brining my car to Nissan vereeniging again.
