Walmart Fraud, Theft Lansing MI

On 3/09/2016 I purchased a laptop on walmart.com and used Paypal as my method of payment. When I got to the store I noticed they picked the wrong laptop and quickly went to customer service to return the laptop. They told me that since I used Paypal as my payment method that the only way to refund my money was by swiping my debit/credit card. Keep in mind that when I used Paypal, I used my bank account to fund it. I did as the CSR said and swiped my credit card, was then advised it would take 3-5 business days to process. The following day I received a call from the card issuer (Chase), and was advised that they were rejecting the credit(refund) because the card was not used initially to make the purchase. I immediately went to the store and spoke to the Store Manager, and she told me that at the "Store Level", they cannot refund to Paypal and I would need to contact walmart.com. When I called walmart.com they told me that in order to refund to Paypal, I would need to ship the laptop to them, completely disregarding the fact that I no longer have the laptop in my possession. At this point I am going in circles, going to the store and then back to the phone to call walmart.com. Where it stands right now, the local store has the laptop, my refund is being sent back to the store from my credit card company, and nobody knows how or when I will get a refund. A refund mind you, in the amount of $338.14.
