Poor customer service

On 16 March 2025 went to spar to buy some items. I wanted to buy a strainer but it couldn't scan and the cashier called the supervisor (Elizaberth) for assistance. The supervisor took the strainer and went to check the price. She came back put the price manually and left. I asked the cashier how will I know if I am paying the correct amount because it was showing non food item instead of strainer. The cashier called the supervisor who didn't even greet me the first time she was called and she just told the cashier to cancel the strainer and left. I asked again the cashier what does the cancelation mean and the supervisor is called for the third time. She sent other lady to go check with the manager. All these instances she never said anything to me, the next thing she tells the cashier to cancel everything and attend the other customers. I was shocked because I am waiting there for spar to solve the issue of the price and the supervisor (Elizaberth) just showed me that she has no intentions of talking to me or solving the issues, she only cared about other customers. She didn't have a word with me until I asked her what is her problem and she responded with a stinking attitude.
