Calling everyday...everyday and sometime 3 or 4 times a day. When you  say "Hello" no body replies.Its nuisance.

Agreed. I haven't had a problem so far and would quit if I did. I don't do unethical - and I don't believe crap from ex-employees who were probably fired for something that deserved firing. I've seen a person fired for accidentally misinforming a customer; we're certainly never told to misinform them, and we do get feedback on our monitored calls.

just received this call (905) 521-9082- I picked it up, not saying a word- at the other end, a few seconds later it was a man's voice saying hello... hello.... He just hang up.

Correct. It's just the automated dialler - most of those have delays and the agent can't always catch the call on time. But I've worked there for a few months, and haven't noticed any ethical breaches, haven't been told to lie, and have been told we'll be fired if we misinform customers. I could care less about workplace gossip. That happens everywhere. And as many of the trainers, supers, and QC people are women, I don't feel discriminated against at all. I'll let you know if that changes, but I just don't see it.
