Oh dear - I fear for the worst.
Kinda on topic but different aggregator - I have been using YakPay to settle our FOREX purchases from AMEX FOREX for several years - last week AMEX FOREX informed me I can no longer settle these FOREX purchases through YP and that payment must come directly from our Company Bank Account.
I summarily told AMEX go screw themselves and I will buy FOREX from another broker who are prepared to accept settlement via YP.
AMEX do have a system whereby you can settle FOREX transactions via an AMEX Card but they want 2.15% Merch Fee to settle - bordering on criminal
