Has anyone else had Myprotein continuously delay a subscription order to avoid honoring an old price?

I'm on an old Myprotein subscription paying £42.75 for 2.5kg. My July 1st delivery was never sent, and my account page has now spent weeks saying it will "ship tomorrow."

CS told me it’s out of stock. But looking at the main storefront right now, the same size is marked up to over £90.

Seems pretty clear they don't want to fulfill orders at legacy prices and are waiting for me to cancel. Has this happened to anyone else? Did you actually get your order or end up cancelling?
