Awful customer service

I am writing to explain about a bad experience I recently had at Wimpy in Hartebee****rt dam Damdoryn, on Saturday the 24th of March. It is appalling to witness an employee, who happens to be a manager of such a respected restaurant behave in such a rude manner towards customers. I went there to express my dissatisfaction about a meal that I had bought on Friday night. It was a meaty feast meal, and all the other types of meat were delicious and up to standard, except for the steak, which was a bit off. I then decided to keep the slip and return the steak the next day. When I got there, the lady at the till told us to wait while she goes and call the manager. We waited for quite some time before the manager could come. Lo and behold, when she came she already had a very unpleasant attitude and told us in the most unfriendly tone that she has tasted that steak and there is absolutely nothing wrong with it, so she doesn’t understand what our problem is. I told this lady that I don’t see why I would go out of my way and drive there, to come complain about something that’s not valid. The conversation turned into a heated argument and I felt much disrespected. I was shocked and disappointed to have been treated this way. When I finally asked her if she was at all going to do anything about the matter or should we just leave, she then said she would refund. She then comes back with a R40 refund. For a moment I was puzzled as I couldn’t understand how she worked it out since the meal cost R146.00. When I asked, she rudely told me I ate all the other meats so that’s the money for the steak. As if that was not enough, she then speaks to another customer about me in Afrikaans and the one word I could pick up was “****en hond”. I trust that this is not how Wimpy does business. I have been to many of your restaurants across the country and the service has always been impeccable, but this, was the most derogatory treatment I have ever received as a customer. I trust this matter will be dealt with and should hope that you respond with a solution to prevent this kind of incident from happening again.
