Bad services

I was at Capitec Bank in Alexandra this morning to enquire about something. The lady that assisted me had bad attitude, did not greet, played with her cellphone which she didn't even acknowledge that I was there. I was extremely shocked as for I've never experienced such treatment of service in my life. I couldn't even get hold of the manager who was in charge. Capitec Bank in Alexandra, is it a norm to treat your customers like that and would you like people to treat you the same way???
