Manager

I had a problem at Pick n pay quagga centre for their service, I wanted to use my smart shopper on the phone using a picture that has a code then cashia told me I can't use it because they no longer use the code I asked her to call the manager and when the manager got there he also told me the something I told him I won't leave without using my smart shopper they will have see how I can use it after all long argument I asked him to scan my card he told me they can not scan then he told ok let's use qcode then I told him ok let's use the website I asked him to come and assist me so that we can use the app but he insisted that I come with him to the office i refused and told him he mast help me there he told me I am making other clients to wait. When I told him I don't want to go the office he mast help me there he said am making other customers late and when I told him his service is bad he then asked for other customers who are on the que to give him their numbers so that if i complain he can call them to come and talk for him. What kind of service is that? When I told him he could have apologised for also inconveniencing me he told me not to make my problem his problem. His name is Tumelo or Tumi.
