Most disturbing customer experience

So I always shop at pick 'n pay on kilburn street in Discovery, Roodepoort and today I had an extremely terrible experience!!! I got an SMS that huggies dry comfort was on special, when I enquired with one of the cashiers she wasnt sure about it so called another lady to help me. From the onset the lady walks to me with an attitude and when I greet her she ignores me and when I ask is the huggies actually on special because I dont see anything showing me that it is. She says ya so now what. So I asked her could you please come show me which one is on special. She gave me a dirty look and made a clicking sound with her mouth. I then asked her is it necessary to be so rude? She turned around and said she will not help and called another lady to help me. I then asked the other lady what's her name and she didmt want to give me her name but after asking repeatedly she gave it to me and said her name is susan! I then enquired by another lady if the lady gave me her correct name and the packer then said no dont give her name! I asked to speak to the manager and he said he will chat with her but maybe she was having a bad day! As if that's an excuse for such rude behavior! As I was walking out the shop she carried on staring at me and I asked her what the problem is and she told me arg and clicked her mouth! I am soooo highly disappointed in pick n pay and cant believe this is the treatment we as loyal customers get! And I will never be shopping there again!
