Not sure but possible scam?

[MO]

Today at about 1500 got a call from an Indian who said he was connected to telstra and that my exchange has just been upgraded for adsl and would I like to connect to DODO broadband.
Now to cut a long story short they are doing the hard sell when they wanted my banking details..e.g BSB,Acct number and name of bank...the alarm bells went off,so I told them no way do they get my details,they got a bit upset and kept insisting it was the only way to get the deal.

End result I said a definite no and hung up.

I then rang telstra to confirm they had a call centre in India it was confirmed,however the person I spoke to said it was sus about the bank details,why did'nt they use my billing details and was'nt sure about telstra pushing DODO.

So hopefully it is now with telstra security am thinking of talking to the local boys in blue about it.

So all dialup users beware.
