Bit of advice if you want to stay in business (not that you will probably heed it).
Go and do a small business course, you might learn how to handle customer issues a bit better.
Don't advertise a product as being one thing then send another. If it was a mistake and you actually thought it was a 044, then admit the mistake and offer restitution, don't go "it's just as good" or try and lie your way out of it. Sometimes you have to take a small loss in a business transaction to ensure your long term viability.
If you have been ripped off by someone else then expose them, it does not mean "oh I got ripped, that means I can do it to someone else"
Don't get into arguements with customers when you have done the wrong thing, admit it, fix it, move on.
Go and see a psychiatrist/psychologist about your "compulsive lieing disorder". If you don't do it now, you will never hold any credibility and you will one day end up on the end of a nasty lawsuit, in jail or worse.
