Buyer Says She is Returning Two Items After 26 Days

[maryrosa409]

I sold two items July 30th in an auction. The buyer paid about 4 days later. I send the items with tracking and she received them about 5 days after. She then began to complain about the items, and asked for a partial refund for the items and $3 for shipping. I did send her the $3 for shipping(as when I converted the money from US funds to Canadian I had excess), then felt that the complaints about the items themselves were not justified, so I said send the items back for a refund.

Now she said she did send the items back but I have received nothing. I feel like I'm being played. What should I do?
