Walmart MASTERCARD Consumer Reviews

I returned an article to a store where I had paid with my Walmart MC. I was refunded the amount of the purchase from the store. Walmart MC input the amount of the refund as a purchase, instead of a credit on my account. When I called, they reversed the dollar amount to cancel out the purchase (erroneously input). Now we are back to 'square one', no problem, no more purchase showing up. Cool. What I can't make them understand: the error has been cleared up, now they have to put in the correct transaction which is the amount of the refund credited to me from the store. I was told, "you received your credit, "Miss Mary". Thank you for choosing Walmart, then hung up, and then I hear please take the survey. Walmart needs to hire some mature people who understand how simple mathematics works. And, unfortunately, yes, they do lie (a lot) but I'll spare the reader the details. Hope a Walmart Exec. reads this, if they care.
