Bad Customer service from the Store Manager at President Hyper Krugersdorp....

I buy my every month groceries there ever single month...On Monday i went there again for my shopping..They had Goldi 5kg on special on the pamphlet so i went to check on the fridge it was sold out...I went to cunstomer care n wanted a rain check the assistant told me she first needs to confirm..Then she was speaking on a walkie talkie to someone n confirmed its sold out..The store manager "Tony" came and she wanted approval to do the rain check..He told her there have replaced Goldi with Daybreak brand i must go get it.She told her i want Goldi and he said chicken is chicken and walked away...if i was white he wouldn't have done that cause i monitor how black customers are treared..is that how you treat customers????cause i felt racially abused..
