Deceived and ****med

This company ****med and deceived me reporting that they are from the government lowering interest rates as I am being overcharged and most of my premium is going into the interest than the car itself. I believed them and sent my details, however it was not all documents. I discovered that they are not trustworthy, I texted them over WhatsApp that I am withdrawing from their offer and under duress they said that I cannot just withdraw, they have already processed my information and they are done from their side. I later received a call that they won't process the application as my documents are incomplete and my identity won't be flagged to the credit bureau. In the evening the very same WhatsApp number indicated that they are done processing my information.
