Sam's Club review: LaHabra, Calif area/ poor customer service that include supervisor that are incompetent.

I have a self-service payment problem seek help from customer service but 4 ladies customer service where helping only 2 customer at a time for "more than 20 minutes"while there are 3 customer included me in front waiting for more than 20 munutes but they seems don't care but show bad atitude toward me with disrespect toward 78 year old asian person. When talk to supervisor he just take our complain lightly and not reprimend those ladies customer service, slow and ineficient. All they know is to fight with you verbally with no manner of calming down the situition.
For more than 10 years shopping Walmart I have never have this kind of bad ill feeling toward the store(Sam'sClub 8 months membership) This customer sevice in front are not showing they love there job, because they are imcompetent slow and not trying even customers are longing for them to make an effort to hurry up !
