I have had exactly the same issues as other people on this site using several numbers and banks even to the level of them saying that bailiffs were on there way to my property which never appeared
Exactly the same scenario as the person on 8th Aug 2019. Stating I had agreed earlier in the year to support local schools etc. Had 2 separate invoices in 2 days from 2 different companies, Different bank accounts, Invoice numbers etc. Reported to Action Fraud
Call from a company called Safety Aware, Lovely lady called Zoe. Safety aware work under MD Limited. She said I had agreed earlier in the year to help support local schools in sponsoring information booklets which I had not! Sent invoice through for £599 plus VAT of would reduce it to £499 if paid today. Had the audacity to keep ringing mobile for payment so reported it to National Fraud.
