How do I get a replacement set of tilt feet?

The pandemic has had me move three times since it began, and the feet labeled '1' have gone missing from storage as they were on the mouse. How do I order a replacement tilt feet? I used the tilt feature 100% of the time and I want to use this mouse again since I'm settled in. Contacted customer support last week, but have not heard a peep from them.
