As a client that has been banking with them for more than 10 years,I’m extremely disappointed and dissatisfied by their service and how they handling the matter I’m currently facing. A suspected *****ulent transaction occurred and they instantly blocked my account,after several attempts of contacting them and trying to resolve the matter and provide evidence.I have been turned back from the branch and everyday I’m speaking to a new consultant that keeps giving me different information. They keep telling me to send emails yet no one responds or gives any feedback.
