How to be a freelancer if the customer does not pay salary?

Question

Design

Good day to all!
15 days ago, the employer (studio) called Avito and offered me a job. All 2 weeks I drew landings (about 5 pieces) and I have to pay 15,000 rubles for payment. (Of course, remote work and everything is on parole - yes, it’s my own fault)
Actually, initially communication was at its best, my level suited me, but by the end of the term, our attitude is getting worse and worse .. it seems that I am a cleaner, not a designer.
Tomorrow is the 30th and they should pay me the RFP, but with the attitude towards me that I have at the moment .. I'm 99% sure that I won't see my money.
Sorry for this "Prologue" but the question is this! Where can I find resources on the Internet for freelancers, where can I leave feedback about employers?
Since I am not the first, I can not be the last. Go to the police (sorry, the police) or the tax office and write a statement .. I think they will laugh at me. After all, everything in words was backed up and it’s just empty to go to the authorities.
I believe that it remains only in this way, on the Internet, to leave reviews about this studio in order to reduce the percentage of deception of other freelancers.
I want to think over the ways of retreat or even advance in advance - it's like the cry of a hunted beast ..

Unfortunately, you are the first, not you, and the last, rule number one and two and three, no relationship without a contract, there must be trust, but business relationships are not built on the basis of trust!
As for the negative feedback about this employer, they will be like a dead poultice to him, if you have a correspondence with the customer and you can confirm the transfer of your work to him, then feel free to roll forward to the site (in the form of a claim) where your work will be posted!
Promise them a charge of stealing your creations since you did not sign an agreement on the transfer of authorship with them, an example of a hit-and-run (gentlemen of commerce, your super cool office in the person of the customer's name stole intellectual property from me, I really hope that you have already managed to save up money to satisfy my lawsuits) and accuse them not as unscrupulous employers but as thieves.
You wrote a correspondence with him, say at the court that you passed on the information for informational purposes, the person abused your trust, and stole the work that you, as a poor freelancer, were then given blood and sleepless nights! And this cunning, insidious and meanest type stole your ingenious creation, and used it for personal enrichment!
I think this will be enough, at least to ensure that your work is not published, and if you also send them a written complaint, indicating the timing of removal from placement and they ignore you, then feel free to sculpt an appeal to the prosecutor's office, for the duration of the investigation their website in general, they can cover up, and it’s unlikely that your clients will want to experience the wrath of the Russian Themis, as you know, it’s easy to block a site in our country, but you get sick of removing the blocking! Success in the fight
