Clicks obviously doesn't want my business

On the 15 February 2018 I went into Clicks at The Grove Mall in Pretoria. I was looking for some immune boosters and a nebulizer. I went to the self service counter and asked what he thought I should get to boost my daughter's immune system as she has a cough and he told me he didn't have anything go elsewhere. Then I found a nebulizer and some medications on the shelves and when I went to find out about saline for the nebulizer I was shown some in the pharmacy but they couldn't dispense I had to wait for a pharmacist. I waited in line for the pharmacist and got told to rather buy a nasal spray, I said I didn't want a nasal spray I needed something for a cough, then she told me to go to the Dr and get cortisone, I said I can't give my daughter cortisone as I am sensitive to it and she is too young for it. Then she **** to me and told me they don't have stock (even though they had shown it to me 5 min earlier). I won't be going back to the Clicks there or recommending anyone else does
