Not attending to customer complaints

I recently had an unsatisfactory experience at the above restaurant. I complained to the manager, who just gave me a very lame excuse. When I came home, I contacted their online customer complaints and received an auto-generated response to inform me that my complaint will be forwarded to the responsible person. I had no response, and contacted them again, without any response.<br> <br> It seems to me that they don't care about customer satisfaction. I predict the beginning of the end with such an attitude.
