California pizza

Hi!
Today i went to California pizza
Kings Mall Branch 2/3 crew totally illiterate
Even don't kbow how to talk with customers..
I've requested for something/info
One of them replied in very casual & misbehavior attitude.
Name tag is not displaying that's why name not mentioned.
Kindly take appropriate action & also verify such instance by assigning your official as a mystery customer.
Regards,
