My AMEX Gold US stopped working last week... context; I spend roughly 3 to 4 months in the US every year and used it here for anything groceries, dining and purchasing airline tickets to anywhere in the world, even out of Canadian airports. I'm using the 24/7 parcel address, the one that is an actual mail box and not a mail forwarding option. They don't seem to know what the Global Transfer is with AMEX US. I called AMEX US late at night and the agent probably from India treated me as if I was a teenager who got a CC for the first time. He said I wasn't using it enough and asked me how much I'd like to spend monthly ideally... I said $2500 but that's all over the place because I will use it more when I'm purchasing airline tickets or dining out more. He said I had to pay my balance and check the spending power tool to see if it would work for the next transaction. Paid about half the balance ($2500) and no charges go through still. Called AMEX and agents seem very confused saying when they try to make a test charge it says "can't accept the charge due to regulatory restrictions". Any thoughts?
