A few days ago I bought a Maclaren buggy for £40 from a popular ad site. The harness straps at the back were only held up by Velcro so whe I put DD in and she leaned forward, the straps would become loose putting her life in danger. The woman that I bought the buggy from didn't show me this and I couldn't go back on the same day as I had to be somewhere. I feel like I've been sold a faulty item and feel like a fool. I'm pretty skint right now so I can't just go out and buy another buggy. I've texted her today but I've had no reply. Aibu to try and get my money back by turning up at her house?
