Unsatisfactory customer

January 2020 I bought a car at this car dealer and all at the time seemed right until I started to notice few errors which i made them fully aware off by sending pictures of the problem. The first was engine sign on the monitor, epc sign and slippery sign. To my surprise now I'm told to fix the car at my cost which infuriates me as I have reported this errors within 2 weeks of purchase. I was then told to bring the car for diagnosis and when requested to see the report on the diagnosis was told it doesn't print. There nothing fixed on my car as the signs are still. I am truly disappointed at the service that I received. I will not pay as I reported in time and I feel de*****ed can you please help.
