I heard back from the bank today by regular mail. ;) Happy to hear from me and about my enquiry. They wanted to make sure they were taking good care of a valued customer. They said "it appears from our research that your mortgage has been discharged". ( I sent a copy of their discharge of mortgage along with my claim of principal)So they basically avoided a direct response to the question raised.
