Engine and Transport Scam

I got this company on the Internet and checked that they have a legitimate website etc. Paid over R8350 for a Motor and once they needed to send the Motor to me I had to pay another R2500 over for Insurance on the transportation through Neo Logistic Service also a company with a legitimate website etc. Got a tracking number and it stated Enroute the whole time delivery date was expected to be 7 oct 21. It's the 12th of Oct today and not one of those companies answer their phones. I have been scammed. These guys operate with legitimate websites, banking details registered to their company names and all. This is really scary.
