HUK doesn’t want to give me TK

Hello guys, last year I bought a car for the summer. Have everything regulated by phone at the HUK, have still 3 contracts, but they don’t want to give me a TK for the car, it is BJ ́94. Is it full. at the car? it is a Mercedes SL 600. The employee at the Tel. meant for such old car ́s we do no more TK. That the HUK my pagoda is not insured is clear to me. I have been insured with the HuK since 1976 and had up to today 3 damages, even theft radio 1983, thief Steeled abroad, not stolen, only damaged 2001, thanks to WFS, 1 Parkrempler 2013. Can anyone tell me anything about it? I found nothing of the kind in the SuFu. Greetings Atzekalle
