is that the way to treat a customer

I went to verimark in middelburg mall to buy a waist trimming belt when I got there the were 2 ladies I ask for the belt they showed me then I asked does its work and they said they didn't call me to come to the shop I can go then asked is that the way to speak to a customer the one lady said icustomer elingenangqodo abayicengi meaning they don't beg a brainless customer!!! Asked for their names because they were not wearing name tags they hesitated and finally said Mbali and Tryphina I don't know how true is that.
