Gleam Technologies — i am complaining 2nd time about service, payment and not solving the problem.

I complained here before (18th october, 2019}. But no one call me or help me. Now say what will i do? Can i say gleam technology is a fraud company. They have no responsibility. At least they can call me. Where is gleam technologies customer support? How many times should i complain here? I called many times but they did not help me. The representative of gleam technologies blocked me on whatsapp. They did not pay.
