Blackworker or “without bill” seller here on MT… What do??

Meal. I don’t know if this fits into the forum, I think rather in current topics but there I can’t make a post. I’m concerned that more and more people are slaughtering several cars and hiring parts of them here. I really like this, not only because they take away customers from me, but also because they post e.g. in the same topic and underbid the price at multiple times. That’s just not competitive. You are then snatched up by w I have absolutely nothing against it when someone kills a car and sells parts of it, but there are some here, which strangely have a part in stock for each car. What can you do against such people? I have a few “known” seats at the tax office, should you just copy such pages and send them to the tax office? Please don’t misunderstand me, but undeclared work can drive companies into bankruptcy, we must give guarantee/guarantee and show the value added tax, in addition we pay business tax, VAT, income tax, workshop costs and and and, since you can simply not keep up with the prices of various black workers, for that you get from us an appropriate quality of the goods and if necessary always replacement when something breaks.
