Misleading information

The main reason I bought my vehicle from a dealership of a respective brand was because I never wanted a "bra Joe" servicing my car. I bought my Polo Vivo 1.4 trendline JC16ZXGP, the deal was sealed in June and I collected the car on the 2nd of July 2019 from Hatfield Rivonia, I bought from them because I thought only a dealership can give me a car they are willing to service especially because it is under warranty. I never knew my nightmare will begin after driving just 7000km with the car. it was on approximately 23000km when i bought it and now it is due for service and Hatfield Rivonia says i should pay R2500 for the service? no one told me the deal has no maintenance included, because I would have not signed the deal if that was the case, I would have asked them to add it. I'm in love with this car, but the main point that made me not to buy from Lindsaysaker, Hatfield is putting me through on a vehicle that's under warranty! I've since asked on a way forward and was since told they will check if they can add the maintenance plan on my deal, I've been waiting since. another thing is why was it not serviced at least before handing over to me at least so i could get the 15 000KM's before having to service. I WOULD HAVE NOT SIGNED THE DEAL HAD I KNOWN THERE'S NO MAINTENANCE INCLUDED. I'm told I have to pay R 19 136 upfront for the maintenance plan to be added, I don't have R 20 000 lying around waiting for nothing in my account.
