I don't know if this is the correct place to provide feedback for this product, so please re-direct if appropriate.

I have ordered family wall calendars (monthly/1 page per month) for many years now and everyone loves them (generally order x 4 for family members). This year however, the paper quality is significantly poorer quality. The calendar hangs with top edges curling forwards. I have tried to flatten the calendar off the wall and re-hang. There is no change to air, no humidity difference, in fact the calendar hangs in the same position every year. I don't want to provide a photo as unsure where this feedback is being sent, or posted, but would happily do so if anyone contacts me from Mimeo Photos. This version and quality puts me off enormously making another calendar this year for Christmas gifts as it could be a permanent paper change? I would appreciate some feedback please.
