Disgusting Attitude of Supervisor towards customer

Was looking for a tempered glass.We had a helpful assistant,but she was rudely interrupted by her senior sitting by one of the computers, a woman probably in her mid 50s. <br> We decided to check out other shops at both ends canal walk.we eventually happened upon the same glass but with a white border at Musica,which was a pleasant surprise as we thought it only came in black, but was more expensive.So we decided to go back to MTN on the 2nd level of canal walk to see if they also had the white version as it would match my white iPhone perfectly.Unfortunately it was unavailable,but the assistant told us we could try other branches in canal walk.So we asked if she could please call them and find out as we gone around the mall 2 times already. She told us she couldn't as she was just a \temp"and would have to ask her supervisor. So she went to the desk where this same senior woman was sitting with another man"
