N1 manager condones bad service and lies

I lodged a complaint maybe two months back about the *** service at N1! Where I ordered from the cashier who didn't bring me the 1st item I ordered. Husband ordered a coffee with cream on top that was off and the woman on duty refused to taste it. No manager in site as she phoned me after getting the complaint maybe a week later making excuses for bad service like oh it was closing time and they need to get transport and making me a **** that the cream was not off! So why didn't they want to taste it!??? And to make a lame ass excuse that they have to get transport to go home because it's dangerous!!! What has that got to do with sloppy *** service???????? Then she **** saying she was going to email me and offer free coffee and the item I didn't get! She never did!! Where did you get the people to work there and this manager??? Off the street??? Wow is all I can say!!!
