3RD PARTY PAYMENT NOT RECEIVED.

I was involved in an accident on the 21st of September and I put through a claim for my self and the 3rd party also claimed from insurance. Everything was approved and my car got fixed and my insurance and the 3rd party reached an agreement of how much they can be paid to cover the costs of fixing their car. 3rd party cooperated well through out the whole process and also sent through her banking details for the money agreed apon to be received at. The payout due to the 3rd party was due to be paid to the 3rd party on the 6th of December 2024 but up until today 3rd party has not received what's due to them. Now 3rd party is on my neck and she wants me to fix her car from my own pocket as my insurer has not paid her. The insurance I'm paying every month without any delays or excuses is not providing the service am expecting when I need it. Can this matter be resolved as in YESTERDAY, please.
