Extremely bad treatment of contractors

Extremely bad treatment of contractors. I was hired by this company to interview candidates in 2023, but Elstefco did not pay me my last invoice for work I've done. I tried for months to get info regarding the invoice. At first they responded that they will look into it and later no response. I sent more than 50 messages on WhatsApp and email over the past 6 months. When i tried calling they blocked my number. And also blocked me on other communication platforms.

I am posting this review because I have no other option, the company does not respond to any query and blocks me the moment I get a new way of contacting them.
