Terrible customer service

I went to the Clearwater branch on 02/01/2018. Got to the till where Nikiwe was assisting, she was standing behind the counter with this long, irritable & unfriendly face. I put my items on the counter, she just grabbed them without even acknowledging my presence or a simple greeting and she started to scan the items. I then asked her how she was & got no response. I went on to ask again "how are you Mam", the response I got was this look that suggested that she was just not in the mood accompanied by a very cold & abrupt "I'm fine". Seeing that my presence was not appreciated, I left the store without continuing with the sale because I will not support any business that treats me like they are doing me a favour. I then called ********** three times to speak to the manager, the phone rings a few times then someone just hangs up. Clearly this is the type of service that one should expect in future from Clearwater branch.
