Forex issues again even without using FNB directly. No response on my complaint as usual

I stopped using FNB directly for my forex because I found their service absolutely **********. I found a company that millions across the globe use and was able to use their services over the past 4 months. Hassle free, what used to take me a minimum of a week up to 3 weeks and numerous emails and complaints like this became a seamless 2 to 6 hour zero effort experience. I paid the $2 with a smile and my money reached SA s****s. It felt too good to be true, and on Thursday FNB decided they don't like this smooth, hassle free process and declined my money stating to that company that my account is frozen. Which is ridiculous, because it isn't. I can move money back and forward from that account so that's a bs story. I have been waiting for a response from FNB's forex department from Thursday. Not a word. The usual bs I have become accustomed to. I honestly thought bypassing FNB would be the solution but they insist on been difficult even if their role is a minor one. I've been told there is no such nonsense from Standard Bank. Maybe it is time I cut ties with FNB. Your service goes from bad to worse. Your lack of remorse or customer service is appauling. You've been a pain in the you know where for way too long. Reading through reviews, I can see the bank is in a downward spiral.
