How not to treat customers

I have always enjoyed Mr Price Sport's active clothes for me and my 2 sons. We never had any issues with service but recently moved to Bryanston. First we went to the "Ferndale on Republic" branch but the music in that store is so loud my wife and I could not discuss what to buy. So yesterday I went to the branch in Fourways Mall. The staff did not care that I was there they were have a very loud discussion about something but I know what I want and pick the two shirts. At the counter there was a lady very loud on the phone and she called twice for someone else to come and help me. When I wanted to tap with my phone to pay I was informed that they do not allowed for tap if the bill is above R500 and I must put through 2 payments. Banks generally does not like for two card transactions to go through at the same place in a short time and will follow this up phone call. So I left without buy anything and bought shirts at Cape Union mart where I felt welcome.
