Just a few points ...
The removal of the roundel etc on the website is done automatically now so it's not as though someone has done it with knowledge that you're trying to renew.
Also, the membership secretary is a very busy woman in her day job so simply may not have had a chance yet.
I know these don't change the fact that you're without your roundel etc but hopefully they might go some way to explaining what is actually happening.
I'm assuming you've sent your e-mail to
membership@ducatisportingclub.com?
