bad service

Hi <br> I went to jet ,just when you enter the store the is a pampers promotion which is all jumbo packs are 150 each , I took a packet and went to the pay points just when I was about to pay them the cashier said the promotion is off i asked for the manager and he said he was the manager and that he won't be able to change the price coz the promotion is off , the manager was very rude and disrespectful he was not polite and told me to go ahead and report him since its not his problem<br> <br> I don't see my self going into that store again the customer service its very bad
