That is a a new one on me. First, I would check the sender to make sure the email is actually from DVC. If from DVC, the second question I have is, "Do you own at SSR?" You mention getting BCV for 1/2/22 to 1/7/22, which is usually something difficult to do at 7-months out and thus I am guessing you own at BCV. If you do not own SSR, then it was impossible for you to make that reservation that begins 1/22/22 since it is more than 7-months out. If you do own SSR, have you checked the SSR contract to assure no points have been taken on that one?
If it is in fact an email from DVC, you need to contact MS and let it know of the error, to make sure you are not eventually charged for the stay and to allow MS to figure out what it did wrong, e.g., did it send the email to the wrong member and that member is still waiting for a confirmation email?. Since lately, it has been near impossible to reach MS by phone, you may want to attempt that communication via the online email.
