Incompetence

What is the point of having online promotions/competitions if you don't brief your stores about it? Today I went to St George's spar Dur CBD to redeem my masterchef stickers that I won online on the sparkznwin.co.za website. Got to the store and the cashier knows nothing about it! Fine.... She calls someone else to assist me this person is clueless too. She calls Raymond ( I'm told he's head of promotions). He too knows nothing about this or they just threw the ignorance card on me. On top of that they both insituate that I'm a *******. Never ever have I felt so small and embarrassed! Asked them to call head office to get clarity. Raymond said no. I should call myself... Okay fine, I ask him for the number and he tells me I should Google it! Well, I ran out of time as I only have 5min to complete redemption of each sticker! Please fix this and I want my 5 gone to the stickers back so that I can redeem my prize again.
