Totyota Financial Service - a 6 months battle to get a simple question answered

In November 2017 I wrote an email to TFS with a simple question about insurance the added to my account. To date 18 May 2018 I still have not received an appropriate answer. We also phoned them several times, sent several other emails. eventually it was suggested we call Hollard, the underwriter. we did - they have no clue what that amount is about. So I contacted Toyota Customer Care. They don't want to deal with this, and referred us back to TFS. Meanwhile there is a second question we want answered.

My experience with TFS is one of the worst with finansial institutions I have had to deal with in a long life.

I will certainly not make use of this service again.
