Discovery Bank ***** department unacceptable service

I received an email from the bank that a ***** case was opened against my bank account. I emailed the bank back with an enquiry to understand why and i did not receive any feedback. I then sent an email to the complaints department and followed all the steps to send the email just to get a response that they cannot asssit as they do not have any details. I mentioned the reference i was given in the subject line as per instruction of the bank and also explaining why i cannot answer my phone as i am out of country but available on email the response i get is they cannot asssit.

This is utter unacceptable service and being out of country and stranded cannot use my account to purchase anything makes one feel vulnerable.
