I used to work as those providers, knocking doors but I'm sure the company I was its legit, good prices for customer y reward for me. Every year a had to sign them up again for new contract. Few years later prices goes up so no more subs. Still I can get the reward if I sign them up, but I dont do business like that, if I'm switching them is to save money, no spend more. It's hard to educate people & let them know how they can save few bucks on their bills. I saw others impersonate as pseg employers to get their bills acc easily but I dont do that, maybe thats why I failed doing that business.
