Facebook complaint: Facebook Sponsored Advert ScamFraud

Facebook used cookies to know I was looking for quality landscaper. Midlands Groundworks advert appeared on my feed. So I contacted them as looked professional. They took £5,100 and are.jow threatening me and I am scared my family is at risk. I have raised complaint to Facebook multiple times and asked for compensation as I have been very unwell over this for past 3 weeks since happening. I want a 4k refund and compensation to get my garden fixed and completed, and for all the stress caused. I need a sage garden and a safe home. The page should be reviewed as multiple landscapers have heard of them scamming families and they are travellers so cannot find them or take court. So I am down 5.1k, unable to sleep or function still, and worried for.my safety. Please can this actually be responded to, as Facebook ignoring my complaints, but I hold them liable for my financial loss and all my distress caused.
