Lack of Accountability and Poor Client Service

I wish to express my disappointment with this institution. I have made a request that they must deactivate my account on their platforms (Apps and Website), they keep on deliberately ignoring my request. I am aware that the NCR makes provision that financial institutions must keep data for at least five (5) years in their records but doesn't give them a right to actively keep your profile on their platforms.

I kindly ask that they remove my profile on their website and app (deactivate account). They can keep the records in their archives.

I have been communicating with this institution with no response or feedback. Please help.
