Bad service

I have contacted VW SA for some information about the warranty on the car. First i was told to send the natis doc as they could not help me.After sending the doc.I asked for info about the warranty.The only info i was given was that the date the warranty expired. I asked for a document showing me what is and what is not covered and was told there is no such document.I needed to take the car to a dealer and they would tell me if whatever issue i had was covered by the warranty or not.My problem with that is as a customer i do not have a document to fall back.If the dealer says it is not covered i just have to take their word for it and leave.I would like a copy of the warranty document so that i can read through it and find out what is and what isnt covered.I was told to take the car to the dealer for the, to have a look and they would tell me what is wrong and what isnt wrong and if it would be covered.Taking the car to the dealer costs money for them to just look at it.
