VW finance/ VW Hatfield

I am puzzles by email I got from them at 23:57 that I got into a variation agreement with them on the 13th December 2025. First of all I don't remember any conversation with them on that said date, and according to my understanding when such an agreement is done both parties must consent and agree. I don't remember anything on that date. I don't dispute my payment obligations but I hate the lie regarding the date on a contract "variation agreement" that I apparently agreed to. If VW finance wants to get me into contracts they should actually call me and there should be records of the true dates not lies. That time am not even in arrears or anything 😒. The last time we talked is when I called them 19 November 2025 to tell them I don't want to be debited on any other date apart from my contract date as agreed. And on top of that the "variation agreement debit is different from the statement debit sent to me on the 06th December and it even shows a tyre warranty amount which i called for and canceled a long time ago. I am not happy at all.
