Barclays Credit Card Complaint

Barclays Credit card department,

Other fee Washington

My name is - - I have an account with Barclay card ( last - numbers - ), it was originally used to purchase - Iphone 5s from - in conjunction with Barclay card stating No Interest for the first ( year or 6 months ), I can not remember which, now almost 2 years later they sent me a notice saying I have to pay in full the deferred interest rate, something I knew nothing about. I just find this to be extremely misleading and unscrupulous. Its not even listed in the normal part of my statements but if you go down alot further in - little section they show it or at least they do now, but if your just checking your balance and keeping track that way no idea, as stated it just seems like a greedy unscrupulous fine print kind of thing
