Clicks poor service

I purchased items at CLICKS the cashier cashed my items and I handed her my clicks loyalty club card and I explained to her that previously I shopped there and the cashier took my club card to scan it but when I looked at my receipt it showed a different club card number which was not mine, but the cashier on this shopping trip to clicks did the same thing. When I looked at my till slip this time it showed another club card number which was not my club card. I'm not sure if the staff are using they own club cards before you get to the till so that points are being loaded on there cards or what's going on. I then asked one of the staff to get me a manager she pointed to the manger said the manager was busy and did not let the manager know that I needed help she then walked away. I then went up to the manager and asked for assistance she told me to wait she's busy with another customer I had already waited for 15 mins and asked her to get someone else to help me. She then told me there is no one else so I waited and until it was closing time only to be told they have to refund everything and redo the sale and she told me this while assisting another customer. I left the store with out being assisted , the service at Clicks Gateway is extremely terrible.
