All the signs point to VMP closing shop abruptly. I’d submit PayPal and credit card claims right now. Records not arriving tells me they don’t have stock on a LOT of titles, which points to money issues. Them having to crowdfund new releases is another, less jarring sign, but soooooo much stuff not arriving is a sign. Also, it appears clear they were unable to pay an experienced IT professional to handle their migration. That it STILL isn’t fixed says they still aren’t able or willing to pay what it costs a pro to fix.
All speculation on my part, but the signs are all there. Cancel any subs before they renew, and ask your payment provider for refunds NOW for all unreceived products.
If you are experiencing a problem now, and ever buy anything from VMP again, it’ll be your fault, not VMPs.
