poor customer service nd incorrect pricing

I should not even be able to lave a star as the Mcds in St. George's Shopping Centre needs to train there staff how to speak to customers....I went for a boeri breakfast and the signage showed R32 and some odds how ever the price went up to R36 witch is not the the problem but both staff and management was rude and refused to serve me if I did not pay R36 but the consumer law states differently so please train your staff I am taking it further end of story
