Well, I can see where things went downhill really quickly. Once conversations get to the point of where you are no longer discussing the issue and converting the discussion to personal insult, then the ability to get to a point of agreed remedy won't ever happen. I don't know how things got to that point, but once things are personal, that is usually it. By suggesting they are calling you a liar, you have left them no out on resolving the issue.
It is interesting that the Armor Tuff only came off the mag extension tube. Why only the mag tube? So the rest of the gun is okay?
Why do you conveniently leave out the specific name of gun scrubber product and only call it a "brand"?
A little research on your part would have revealed the fact that Armor Tuff is neither.
