Service way too bad

I went to Wimpy Riverside mall, Nelspruit, Mpumalanga the service there SUCKS they serve you like they doing a favor, what makes the situation worse is that I reported to their head office and They did not bother to get back to me despite the emails that were sent back and forth am so disappointed, except that they only sent a case number in both the head office and the this particular restaurant, The head office can refer to case NO...
