Startec Global Communications review: The company didn't warn me and closed my account

I had the account in Startec Global Communication. I didn’t use it within 2 months and when I tried to open this account, the website showed that my account was closed. I immediately contacted the customer services, and their agent informed me that as I didn’t use the account, they were entitled to close the account and keep my money. I tried to persuade the agent, but everything what I told was useless.
