I've been using Forex Broker CashBack for a few months now.
What can I say? Well the customer service really is excellent! I had a problem with one of my broker accounts (it was my own fault) and the Forex Broker CashBack support team bent over backwards to sort things out for me.
Other than that, the system is very easy to use and understand, I like the reporting and the payments come through right on time. 😄
