Western Union MTCN Code Invalid - Funds Stuck for Over 3 Weeks

I've been attempting to withdraw my Western Union funds using the MTCN code for more than three weeks, but unfortunately, I'm still unable to access my money. Despite the sender's repeated assurances of fund availability for withdrawal, I am still encountering difficulties. I reached out to Western Union customer support, and they assured me that there are no issues and that the funds should be accessible. Unfortunately, the funds are still trapped in my account. I've also reached out to my bank, and they have confirmed that there are no problems from their side.
