My 'broker' IronFX offshore is demanding a 'platform upgrade fee' before I can withdraw. Is this legit?

Hi everyone, I'm really panicking here. I've been trading with this 'broker' called IronFX offshore for about 6 months, mostly forex and some commodities. Everything seemed fine, I even saw my account balance grow pretty nicely, at least on their platform. I decided to try and withdraw some of my profits last week, just a small amount to test the waters, about £2k. My 'account manager' (who's been super pushy btw) told me I couldn't withdraw until I paid a 'platform upgrade fee' of £500. He said it was mandatory for all accounts to access the new, faster withdrawal system. It sounds completely dodgy to me. I've never heard of anything like this. Is this a common thing with brokers, or am i being scammed? What should i even do? I'm worried about losing everything.
