DISGUSTING CUSTOMER SERVICE

Yesterday I went to Clicks Bellville Central, Western Cape to buy a pressed powder, I also decided to buy a setting spray from smudge but I saw Maybelline's setting spray at R69.99. When i went to the till it scanned R169.99. I told the cashier that it's R69.99 as the price was there on shelf : LASTING FIX setting spray 69.99". I went to double check though I was sure, yhooo!!! Security lady came and was like "no no no thats not the price" followed by a manager, that was extremely rude. I took the pic for proof. As I want that spray for that amount now because of their stinking attitude towards customers
