I was overcharged by Walmart. I made several purchases online for Christmas presents in early November 2014. I realzed by the end of November that they had overbilled me and have been getting a run-around from one customer service agent to another. I was then told to contact their billing department who has not bothered to respond. I sent my billing statement from Walmart and my Bank statement showing the problem as requested and still nothing. I will never shop at walmart again.
