Clicks had a 3 items for the price of 2 special, which did not register at the till point. I pointed this out to the cashiers, one of whom went to look and came back to put the special through, but I was given such bad attitude and two of the cashiers even commented to each other about me. As the customer I should have the right to not only receive the specials as advertised in the store, but also to be treated with respect by the staff of the store, especially considering that the fault was on their side and not mine. Atrocious customer service! Very disappointed, as I usually enjoy great service from Clicks.
