We relocated back to the UK in Dec 2013. My mom who is 79, received her American pension via direct deposit into an American bank account, which I withdraw in the UK on a debit card. We didn't notify the social security administration when we left as it was all done hastily, and due to it arriving each month all was good. They just however altered the payment amount to less than half. In the USA she was receiving her British pension and I notified them when we arrived. I'm afraid we did the wrong thing by not informing them before we left and am unsure as to the best way of sorting this now problem out??? Any advice is appreciated.
