I've raised £250 to Help Alexa beat the scammer!!

My 13 year old niece saved and saved her pocket money, Christmas money and birthday money so she could buy herself a phone for her birthday... her mum and dad topped up the rest and entrusted a man selling an iPhone for £250 on Facebook market place, This man has now disappeared off of the face on the planet and left my niece penniless, phoneless and completely distraught just before her birthday, with her birthday being just after Christmas we cannot afford to replace the money that has been stolen, but maybe with a little bit of help we might just manage to make her birthday worth while to brighten up this little girls day. She's has such a tough year and this is the last thing she ever needed 2 days before her birthday. Please help us to bring joy to alexa on her birthday rather than more hurt and upset!
