<prompt> Human: So I purchased something using 2 credit cards. I maxed one out and put 200 on another one. The item I purchased was not exactly what I ordered so the vendor agreed to refund 800 back on my card. Rather than refund the card that I maxed out, he refunded 800 on the card which I charged 200 on, resulting in a positive balance on that card.I dont think this is an issue but... would there be any issues with this? Obviously, the card company with the 200 charge does not know about the large purchase on my other card so to them it would seem like a vendor charged me 200 and then refunded me 800. Would that not raise red flags? Im pretty sure I can explain it quite easily and I have all the documentation to prove that this was a simple mix-up, but I dont want to deal with this anymore and I just hope that everything is done. Thoughts?Edit:Thank you all for the quick responses! I use the refunded card a lot so there wont be a positive balance on it for much longer haha. Glad I can finally put this behind me.  <response>: No issue. Happens to me occasionally. You can either spend up the balance, or if you dont spend more on the card, the CC company will cut you a check for the negative balance.
