Rude staff

My baby uses Novalac AC, this product is not kept in stock at Clicks Caledon. A few weeks ago my husband went to the store and asked them to please order the formula that we use. we received a phone call a few days later confirming that they received some of the formula. I then phoned clicks again a few weeks later and asked them to order new stock as we have used all the stock that they ordered. They informed me telephonically that they will attend to my request and revert to me. I received no further communication, so i went to the store and asked them if they have managed to order the formula as requested earlier. I was informed by a very rude lady that I can't just come into the store and ask them to order something for me as that is not how the process worked. i then informed her that we did already order in the past and that i just want to re order the same formula. she kept saying that i am in no position to come into the store and ask them to order something for me. I now have to go to Herm**** to buy my baby the formula that she needs as the staff of Clicks Caledon does not want to assist me in ordering the formula that i need.
