SMS informing that account is frozen

I received an SMS stating that my account has been frozen and I need to go to any branch with ID and proof of residence.<br> When I went to the branch the very helpful manager checked all my accounts and none had any problems.<br> <br> How dare the bank send a message like that and with absolutely NO information regarding which account. It could have been a business account even.<br> <br> What would have happened if I was out the country?<br> Why no previous sms informing that you have 10 days to sort it out?<br> Why even send an sms when the accounts are all correct?<br> <br> It seems it was NOT a hoax as the contact number on the sms connected to the banks stupid telephone call centr
