Urgent Complaint Regarding Poor Service Experience!!

I am writing to express my disappointment regarding the service I received during today’s call to your Premier support centre. I contacted FNB to follow up on an issue caused by the bank. During the call the representative named Sifisosakhe Dube informed me that I would be placed on hold while they spoke to their manger. Unfortunately, I remained on hold for over an hour without any assistance or updates and eventually had to hang up. This experience was extremely frustrating and unprofessional. As a customer I expected timely and respectful service, especially when the issue originates from the bank. The representatives lack of communication and disregard for my time does not reflect the standards I associate FNB with. I kindly request that this matter be investigated and that appropriate steps are taken to ensure this does not happen again nor to anyone else for that matter. Additionally, I would appreciate an update on the original issue that prompted my call. Thanks
