Walmart Poor customer service

I bought a riding lawn mower on 5/03/13.It had no operator’s manual with it. I called the store and was told to come in and they would get me one. I did that on 5/5/13. I was told from the person in lawn and gardens that I would have to come back the next day and speak to the manager. I went to the service desk and asked to speak to a manager and the manager was called but didn’t come to speak to me. He said I would have to go to lawn and gardens for help. I don’t like the run around. I left the store and looked it up on the net and within 3 minutes I had what I wanted a manual. This is poor customer service and I’ve worked in the public for years. I spend a lot of money at Walmart a month but will think twice before I go again.
