Just a heads-up to JH residents:
A few days ago, someone from IDT showed up in our building and was knocking on doors, trying to get people to hand over copies of their ConEd bills to "check to make sure [we] weren't paying sales tax," and basically trying to fast-talk the tenants into signing up with IDT as their energy provider. I interrupted him confusing the hell out of my neighbor, who is in her 90's, and made it clear that unsolicited sales calls were not welcome in our building. I "escorted" him out, and fortunately, he was polite about it and left quickly and without a fuss.
The blog Consumerist has been following IDT, the failed calling card company which has re-framed itself as a shady "energy reseller," and their not-so-fair dealings in detail, so I won't rehash everything they've very explicitly spelled out here:
http://consumerist.com/consumer/idt%20energy/We have a lot of elderly residents in our building, along with many people for whom English is not a first language, and it seems that IDT regularly sends their "representatives" to places like this because they see these people as easy targets.
I'm not saying that energy reselling is necessarily a bad thing, but consumers deserve to be able to make educated decisions, not to be harassed by unsolicited sales calls, or to be fast-talked or tricked into handing over their utility bills and personal information to a stranger, or to be manipulated into signing something they have not been given time to study or consider.
Please keep an eye out for these guys, and send them packing.
