As you state you have not pestered them, my best advice would be to start pestering them. At least to get some clarity around the situation and what your expectations should be, then hold them to whatever commitments they are able to make around due dates with continued pestering running up to those dates. Trying to back out of these things is probably difficult due to the more complex nature of the arrangements and the parties involved, but not something I have ever tried to do. I had a similar situation with multi-month delays on a C2W during covid supply chain disruption period, and just waited it out (as I didn’t really need the bike as such) although I was obviously not happy to be having deductions from pay each month with nothing to show for it
