I have been looking for a long time for a way to get back the money I was not paid by one company. I bought a subscription to an educational course, but they never gave me access to the materials. Support responded with vague phrases and then stopped responding altogether. I was about to resign myself to the loss, but an acquaintance advised me to contact debt collection https://www.grandliga.com He said that this company deals with refunds in such cases. I decided to try and left an application on their website. The manager contacted me, listened attentively, asked for documents and said that the chances of a refund are good. GrandLiga specialists took matters into their own hands, prepared official applications and started the refund procedure. A month later, the money arrived in my account!
