This should be expected since you just removed the volume group.

The PV was already removed - hence the "not a PV" error.

Nothing went wrong.  What are you trying to do?  

If you want to create a new VG from scratch, then start with
pvcreate /dev/sdc2, then do vgcreate -n NEWVG /dev/sdc2.

If you wanted your old VG back, you've got problems - since you just
deleted it.  If you have a metadata backup, you can install it with
pvcreate.
