Cox has been charging me extra.

I've been enrolled in Easy Pay, for convenience, since January of 2026.  A week or two ago I noticed Cox charging me different amounts two or three times in one  month.   Cox's statements do not show those charges, my bank says those charges went to Cox according to their system tracking system.  according to their records.  So who is pocketing my money ?  Is this an inside job? For now I cancelled that easy theft system.... still working with my bank...
