Shocking Bad Experience customer service KFC Boskruin

A very shocking and unpleasant experience at KFC Boskruin branch Johannesburg. We ordered the KFC Bottomless Bucket in order to qualify for an entry into the competiition that is currently been advertised all over TV Social media etc. To my surprise when I asked the Cashier helping us about what we can win with this competition I was told she had no idea about this promotion and did not even bother to find out more from fellow colleagues. We were the only ones in the branch at the time no other customers and had to wait 20 mins for our order. I believe the promotion has a special KFC bucket with a promo code on it which did not happen with us so we lost an entry . My partner and I received our order and we were not offered any serviettes or the normal regular salt and other sauces accompanied with your meal. When we complained she had a terrible attitude and was busy speaking about us to other workers in her own language and basically ignoring our complaints . Is this the type of customer experience we should have from a world wide recognised Franchise and staff not trained fully for knowledge of promotions and so forth. I will never go back to that branch again due to this .We were at this branch on 03 May at 19.23 Order number 1344
