Barclays Bank Finance Platform Denies Account Access With No Support Response

When I try to log into my account through the Barclays Finance market dashboard, I receive an “invalid credentials” error. This issue started last night, and since then I have been unable to access my account. I currently have a balance of $41,300 in my account, and I want to withdraw this money. I tried methods such as resetting my password, but nothing worked. I attempted to contact customer service, but I did not receive any response. I am receiving services from Istanbul, and I request that my grievance be resolved, my access to my account be restored, and that I be given the necessary support to withdraw my funds.
