I faced a similar situation on MU202. Airline did the same thing to me and failed to notice I would miss my connection until I pointed it out. They offered me a choice of a LHR flight the day before giving me a rather long layover in PVG or to fly my connecting flight the next day, with similar results.

I asked for the LHR flight a day earlier but by the time they had replied, this had also been withdrawn from the schedule and I am not able to arrive 24 hours later so was faced with no choice but to cancel & rebook elsewhere.

They firmly said 'no hotels'.
