Broker Features - Forex Broker Testimonials

So here is my story. I have been working with ThinkMarkets as an IB through my Forex cashback/rebate service. At the time, ThinkMarkets IB commission rate and also an increased rebate after a few active clients. 1.5 years later, when we reached the required number of clients and I wanted to talk about the increased rebate and request my first withdrawal. Instead of the increased IB commission, I got an investigation and a message from their partner department that after 2 clients (and their trading accounts) ThinkMarkets was not able to pay the generated IB commission. Turns out this client was also an IB partner. I have no idea about this. I requested additional information about this case but I got only a paragraph that was not valid for this case.
