Trent Oaks Patterson Capital Management review: Investment scam 1

I was called by an individual from Trent Oaks Patterson Capital Management (TOPCM.com) and a lucrative investment was offered. I researched the opportunity, as well as the company - all looked above board. I decided to proceed and invested $10 000 USD, which was minimum amount. This was in 2018. I received share certificates etc. and received access to the website (www.topcm.com) with my own login details, and was regularly contacted with updates. The contact person eventually handed over to another and later another. In each case the person was very well spoken and very knowledgeable on the financial front. Later, another offer was put on table with which I could yield good returns. I invested a further $10 000 USD. It was when I wanted to withdraw some money, that the issues started. Firstly, I was unable to withdraw due to compliance issues with my account. I was told that the best would be to close the account, then re-open a new account, then do some further trades, then I would be able to withdraw funds. This was then actioned by my contact and further trades were made, but on the first new trade, there was a trade shortage of $2500 (approximately). I had to pay this to bring my account to zero, which I eventually did. The next thing they were going to repatriate my funds, but I got a phone call saying that the intermediary bank took some fees off, so the full $2500 did not arrive. The company is now migrating to Japan and there will be an additional $1000 migration fees. This is where we are stuck - hence may opinion that it is one great scam, and I should never have paid the last moneys.
