If you don't have an account, I wouldn't recommend even opening an email from them.
Nope, I wouldn't, either.
It's not the first time I've gotten emails regarding overdue accounts, hacked accounts, account offers and bonuses for accounts I don't have. Not that I get many these days [spam filters, etc] but I used to get bonus offers and increased limit offers for being a valued customer.... from credit card companies I do not have accounts with. In fact, I refuse point blank to have a credfit card [debit card only] so all those bogus emails went straight in the bin, being that all they were after was my bank account details.
Another scam I used to get was a bank - any bank/financial institution - telling me that my online banking had been hacked. Yeah, right! Just another thief looking for bank account details... but once I saw the title, and that it was from a bank I did not do business with, I binned it immediately.
Funnily enough, I haven't won the UK lottery recently, nor have I been selected by a Nigerian prince to safeguard his cash in my bank account for a generous sum of money to compensate me for my trouble. I miss that! Yup, I spent the last $4.6 million on Coca Cola and chocolates and need to boost my coffers to feed my addiction.
