Customer treated like ********

I went into Eastgate to do a sim swop after a hijacking. I was assisted by a very helpful young man but the Mangers attitude was shocking.....she first question the legitimacy of my ID as the photocopy quality was poor.....When I suggested the copier may be at fault was rudeness of the highest level. She humiliated her staff member . When I took a photo so that there would be no mistaken identity issues when I made my complaint she as even more aggressive. She then made disparaging comments about me to another customer. No customer wants to deal with a sour manager in a customer service environment.
