We bought our bugaboo frog from ebay. I really wanted a parent facing pushchair that could fit in our corsa but we couldn't afford a new one. Now typically its broken (the buttons you press in to tilt it dont 'pop back') customer services arent repling to our e-mails, John Lewis (who sell bugaboos) say we have to take it back to where we bought it from but as we bought it 2nd hand we cant... anyone any ideas?????
