Terrible service, constant empty promises and untrue information

I have had the worst experience with Supersonic.

I cancelled my contract with Supersonic in April but they only collect the router in June cause than they could bill me extra on my account with them.

I have been calling them, messaging them, emailing them and inboxing them for the past 3 months with regards to the reimbur*****t for the router but nothing has been done.

They just keep saying they will log it with billing or waiting for approval, some people said I will get payment in a week and this was weeks ago.

This is completely unacceptable and terrible service.
