Unprofessional & rude employees, time wasting emails

"Good day Please take it up with the merchant, as you have spent [sic] 9days at that [sic] accomodation Regards"

This email above, was sent to me by FNB's dispute claims department. Since I’ve had enough of being treated like a third-class customer by FNB, I have decided to publicly air out my grievance with FNB and the employees in question. This shockingly, unprofessional email is a fine an example of how FNB has treated me in in the last month & it gave pause to the point, I am now considering closing all my accounts with FNB.
