Someone bought a breast pump from me that was in fully working order 40 days ago from me on Vinted and left positive feedback at the time. Today she has contes me saying it worked well for 2 days then apparently randomly started turning itself on automatically and now won’t work at all. She is asking for receipts so she can try to get a repair from the manufacturer. My receipt is out of warentee and wouldn’t cover her for repairs anyway even if was in date as she has bought it second hand. I feel the most likely scenario is she’s used it, breast feeding hasn’t worked out for her and no she is fleecing me hoping to get her money back. Even if true she has waited until 40 days post purchase to raise a concern. I assume she has no right to refund and is past the point of being able to leave me negative comments or feedback that could affect my future sales? Thoughts appreciated for information she bought the breast pump for £35 including all the accessories which retail around £200 new
