To further chime on this, guys, do give good feedback/compliments back to the company for good CS. Bear in mind when we need help, CS is our first base.
Imagine you work as CS, you do job well and dedicated. Sure it is your job, but getting compliments and feedback from customers will help with their KPI. Of course their KPI is keeping customers happy, but if customers don't feedback say they happy, they don't meet KPI..then they ask themselves..i work so hard, work so well, customers also don't appreciate..and i don't hit KPi anyway... why bother? and that's when they become sloppy..
which in turn make OUR LIFE difficult.
So yes, give feedback and show appreciation to their company if they do a good job. A simple email to the company stating the name and brief description (which takes 5 minutes of your life) would help them a lot.
can.. but better use MBB 2 Card AMEX to pay those..got 5%...
Depending on your spending pattern.. Watami may not be suitable and MBB 2 Card may make more sense.
