I want my money

I wish I could select zero stars, but i does not allow me too. Went to tygervalley mall Macdonald's on Sunday, and its one of those you cant complain about the service because there is no service. I am still waiting on a refund that I was told would be in my account by today??? Your manager Mbali does not know what customer service is. I would like my money back as promised since I did not get an order as it was cancelled due to the poor service from her.
