Gosh as someone's whose worked in a similar environment to poor Jessie here it just boggles my mind that you would keep going on and on and on when it was clear they weren't going to give you what you wanted. Like was being that much of a pain in the ass really worth it?
It took 3 hours before I became a pain in the arse.
3 hours of being a very patient customer.
After those 3 hours, customer service still hadn't fixed my problem.
Did you miss the parts where she lied to me?
Where did you work where that sort of customer service would have flown?
