Extremely Poor Service and Unauthorised Debit Check Leading to Account Block

I am writing to formally lodge a complaint regarding the unacceptable service I have received from my bank.

A debit check was conducted on my account without any prior notification or communication. As a result, my account has now been blocked, causing significant inconvenience and disruption.

I have spent over 3 hours on the phone today trying to resolve this issue. At one point, I was left holding for 40 minutes without any assistance. Throughout the day, I was repeatedly transferred between different departments, none of which were able to provide clear answers or resolve the matter.

After an entire day of trying to get assistance, I am still left without any explanation as to why the debit check was performed without my consent or notification, and more importantly, my account remains blocked.

This level of service is extremely disappointing and unacceptable.
