They are also being sued for "funny business". Excerpt from a local online news source.
"The Consumer Financial Protection Bureau has filed suit against Capital One for allegedly misleading customers about its high-interest savings accounts.
The suit, filed Tuesday, alleges customers were cheated out of more than $2 billion in interest through Capital One’s flagship “360 Savings” accounts. The accounts were advertised as having the nation’s “best” and “highest” interest rates but instead were frozen at the lowest level even as rates rose nationwide, the Associated Press reported. While rates were frozen, Capital One created “360 Performance Savings” accounts that saw higher growth – at one point paying more than 14 times higher interest than 360 Savings - but the product was not openly offered to many customers, the suit alleges."
