Mugg and Bean with no service

on Sunday the 1st of December I went to the Mugg and Bean at Springs mall with my sister and her daughter. I was not at all happy the service I received. Firstly I had to get up and go search for a waiter after waiting minutes for someone to come an assist us. I am on the Discovery vitality programe and wanted to redeem my points to buy smoothies for myself and the people I was with, the waiter advised me to redeem them only to be told 5 minutes later that their scanner for the QR code is not working. honestly this is unacceptable, the system issues should have been advised to myself before I redeemed my points.

the overall experience was very unpleasant.
