Bad customer Service

I bought a polo vivo 1.4 trendline 2018 its been giving me a problem with an epi light and I have reported it at the dealership they fix it then it comes back again. Today marks the forth time its appearing they took it a gain to fix again.

I called the dealership to ask how far they are with it only to find it wasn't even touched leaving without mobility my car is still under warranty. I called again Victor the service mgr said they don't have a car for me to us to get home and they are not magicians to fix cars takes time As a customer I feel that vw doesn't care about us I use my car as a family vehicle so I transport my kids with it to school and me to work. For them to tell me its not their problem how I get home doesn't sit well with me .I am costumer I need to be treat like this with such manner.
