Today HSBC sent me a letter with a calligraphic certificate stating that being a priviledged customer, I am afforded a pre-approved personal loan. In that certificate they have stated my bank account number. Given the fact that this being sent in a snail mail/courier, it could have well landed in some wrong hands, exposing my account number.
For the sake of their marketting campaign, I cannot afford to loose my credentials. On the part of the bank's security lapse, I seriously condemn their carelessness in revealing customer credentials.
