Bad attitude

I bought an Apple MacBook Pro 13” for 24K yesterday 24 December 2017 and that same night I followed a free upgrade path to High Sierra OS. The upgrade downloaded, installed and rebooted. It then said upgrade failed and doesn’t want to boot any more. I brought it to Eastgate Apple store. Guess what, they want me to pay before they will look at it and I must make an appointment. After being a defending supporter of Apple, I must say I am sadly disappointed in this store and Apple.
