Shocking service !!!

I purchased a dell laptop from Makro online on the 23 October 2019. See attached invoice and laptop service tag number. The laptop stopped working and won’t turn on at all. I went onto Dell website as it is still under warranty . To my surprise when I enter the service tag number, according to Dell’s records the warranty expired April 2020 as it was sold March 2019. Very confusing as I only bought the laptop October 2019. I returned it to Makro but they asked if I could contact pinnacle warranty, directly to arrange the repairs as it is still under warranty. Pinnacle in return has referred me to contact Ensure. I am being given the runaround I need the laptop to Earn an income.. so your urgent response will be appreciated Regards Shouneez Sasman ***
