Flex Bix

I was sent a flex box that I didn’t ask for. I called and was told that it was free, mine to keep, and there were no worries. I didn’t even use it and got rid of it. This was 4 years ago. Today I cancelled my service and was told I would need to return it or I would be fined. I didn’t even know what he was talking about at first because it had been so long. Biggest scam, will not ever be returning as a customer.
