I've had an DJS AMEX card since it launched & original life of balance BT . Tonight, I found a letter from AMEX saying they had reviewed my account and decided to dramatically lower my limit. I've never missed a payment & apparently been with them for 19 years. Only other product I have is the gold charge card which I don't use but have kept paying the annual fee on. Has this happened to anyone else? I had a large unutilized limit and have other cards where I've been warehousing limits. Can they do this without cause and is this likely to happen with other issuers?
