Disappointment and worst service

Went to Game N1 City and while we were there my son saw a Robot toy he wanted. We bought him the toy. When we got home the toy did not work. My husband went back to Game to return the toy. When my husband got there he was refered to the refund counter where he was helped by Joyce. Very nice and helpful. Once they established none of the other toys they tested worked my husband asked for the manager. That's when all went wrong. Chesca came walking to Joyce and shouted "what" Joyce told her the toy is broken the customer wants to return it then Chesca shouted "what do you want me to do about it". Chesca did not see my husband before that moment standing at the counter. My husband then turned around and told her he wants her to sort it out. He then asked to speak to her manager as she is rude. She changed her attitude and wanted to assist two three times after my husband asked for her manager. Then Mr Sait came to assist. One would expect better service from a manager seeing as the customer is already upset with a defective product them still have to experience bad service. A manager should never speak to an employee like that and especially not infront of customers. Worst service ever. So my husband returned very disappointed having to disappoint his son and we had a child that was upset and disappointed because he wanted his toy. I wanted to wrap it for Christmas but my husband insisted we give it to him now. Imagine we had to face this disappointment on Christmas. Game will not see us anytime soon again
