Poor customer service

Shoprite is known for slow service, long ques, we used to it by now, but today im not there, on the 15 march i went and bought 5kg mixed portions, as i was about to pay i realized i ddnt bring my card so i used my banking app to pay,

First transaction declined, tried again and it went through but unfortunately it deducted twice on my balance. Went to management and i was told to wait till balancing is done or until it appears on my statements.. Sharp

Come today i go back and enquire since it did not reverse, found a controller who was trying to help, she went back n forth from me to het admin manager delivering messages betweus whereas as the very same manager kept passing me and never bothered to even talk to me and avoid sending the poor controller back amd forth.. I was told she said her books balanced, so the least she could do is call the bank.. Thats its. Did not take my details so correspondence or anything she just paddeand left. When I asked how will o know how the call weng amd when to return. I was told they do not know. The ladys name is lerato. A manager /admin at shoprite lydenburg,A person whose aim is to please did not even acknowledge me
