Car finance inconvenience

I started my car finance application on the 15th of this month, my application was finally approved and I was advised that the seller I am purchasing from was called this morning at 11am. He was advised that he will receive an email immediately regarding what is required from him, he has still not received this email. The person handling my application has assisted poorly during this process- never providing when promised, constantly unavailable. I have been calling daily since last week and can never get hold of her.

I need the email promised to the seller to be sent immediately so this process can continue and be concluded.

I would like to be called or emailed once this has been completed as I cannot be calling FNB/ Wesbank everyday following up.
