Two months ago I started to conduct an investment-based immigration program to Bulgaria with the aid of a Bulgarian law firm. After two months, I found they were extremely unprofessional (the bilingual documents provided had typos, many duplicated articles, even Google Translate results) and there were also hidden fees after I enrolled. I tried to negotiate with them for refund, which did not work. I started to question them for fraud and noticed them that I would ask for chargeback from my bank.
Then they sent me a quite threatening email, which included notify the embassy, file criminal complaint in Bulgaria, and some stuff about bilateral agreement between US and Bulgaria for lawsuit.
Some facts: 1. We did not sign any contract for the immigration service. I only provided them the scan copy of a lot personal documents. (Passport, no crime certificate, etc.) 2. The total number I asked for chargeback via my bank was around USD 11,000. 3. Currently I lived in the United States, but not a US citizen or PR.
Can they take legal action against me? By what method? In future, when I travel to EU (or even do another immigration program), will I get into any trouble if they really sue me in Bulgaria? I'd like to ask for advice for this situation.
