I Need assistance and I need someone from the credit card department to contact me

I have been seeking for assistance since the 26th of April, I asked for payments to be allocated no 1 is assisting, I asked to update my bank details no1 is assisting I am being transferred from pillar to post, the chat on the app is even worse you speak to 5 different consultants and no1 resolves your query. I sent an email to complain and there’s no reply.
