Click need to train their staff / Wake up

Yesterday I went to clicks to clicks at Littleton in Centurion. When I got to the till points I could not pay as I was told that Clicks does not support the SAMSUNG PAY app on my android phone as method of payment. I had spoken to a few people there but everyone kept looking at me as if I was from another planet when I was explaining how the app works. Eventually I took the medication back to the dispensary and there I was again told they do not support the SAMSUNG PAY app. When I was in my car I called the Clicks customer care line and was assisted by Khanye (I believe) that also told me that Clicks does not support the app at all. when I told him I would like the option to choose how I was going to pay he told me it is the company's prerogative to decide what forms of payment they want to allow. When I wanted to lay a formal complaint I was told there is not really a complaint to take from me. Today my spouse went to the same clicks store and used SAMSUNG PAY to pay for his medication. I went to the Clicks store in Hyde Park today and also paid for my medication there by using my SAMSUNG PAY app on my handset. PLEASE PLEASE PLEASE, train your staff. it is appalling that a company like Clicks do not train their staff correctly regarding payment options and how to use them. this is 2019 people please. Get with the times.
