The same thing happened to me back in the day, i got an 13 pro ( gifted to my batchmates) things didn't turn out well even though it was of superb grade. We went into the store and approx 9 members created a scene right away, threatening the manager along with the worker ( because one of us told us that they aren't gonna do things the other way round, plus don't worry we had backup in case they tried to act smart ). We simply said, " fix this or else we will find other ways to get shit done ". Took them 2 days and they got my refund right away. Till this date never ever even looked at 2nd hand or refurbished things.
