I have a UK Amex. I have disputed charges via a lawyer on the card which I did not make and Amex credited back these charges then reversed them. The amount is substantial and over £50k I have also had foreign transaction fees added to the account I knew nothing about. They now want payment and I'm refusing to pay as I do not owe them the money. I have lived in the US with a US address on my UK Amex account for the past 6 years. So am not a resident of the U.K. As I'm at a deadlock my account is now due to default soon and I will owe them over £50k. Can Amex enforce card debts in the US if signed in the UK with a UK credit agreemnt for UK. Will they take me to court in the UK or US and what will happen next? Im not running away from the debt but want to know what will happen next or what I should do.
