yeah thats what exactly happened to me today which is a real pissoffff

We called Rogers and they informed us that the reseller that owns this number is IRISTEL  - (416) 848-9804. We called them and were informed that they have the number belongs to one of their resellers, who by now could have further sold it to another reseller, and so on and so forth.
The woman we spoke to at IRISTEL was helpful and said she'd look into getting our number removed if she could (we called after hours). Let's keep our fingers crossed (these calls are SO IRRITATING!!)

I received several calls by someone that called himself John, very persistant and very rude, saying he was from some phone company, he wanted to get personal information such as credit cards and sin numbers from anyone so he would give some kind of a deal, I did not give him any information so hegot upset, I find this type of calls very suspicious, how can I verify if this is authentic.

Yeah, try to call them back. Either the line is dead or you get a message from the operator saying: "Your call cannot be completed as dialed" or the retro 70's "all circuits are busy" message!
