Poor service and incompetence

On 7 August 2025 I paid the full outstanding amount for my credit card and sent a request for account closure and a paid up letter. The consultants keep sending me from pillar to post and no one is giving me an answer regarding my request. Honestly it’s both discouraging and distasteful to be passed from one agent to the next without any assistance and when I request for a direct number to where I’m supposed to call, I’m told there’s no number and I must send an email. I HAVE SENT EMAILS BUT DONT GET ANY RESPONSE!!! This is so Frustrating!!!!
