Caller: telemarketer

I was suspicious of this number and didn't pick up. After receiving multiple calls, I decided to call it back from an unlisted number. Just as I thought - it was a telemarketing company with "great offers on Electricity and (other) offers"
Don't bother picking up, just block straight away.

The number above is one of a series of numbers which I believe are all linked to a call centre I know not where. Irrespective of the number they call me from the conversation goes along the following lines: The caller says "Hello Mr Tran" and tells me that they can save me money on electricity bills at my home in Prahran Vic. I point out that I am not Mr Tran, I don't know who he is, I do not live in Victoria and they obviously have a wrong number. Sometimes they apologise and promise to delete me from their calling list. On one occasion the caller asked me to pass the phone to Mr Tran! This is an ongoing annoying situation. It seems the call centre has been sold a list of people to cold call and somehow my mobile number is on that list against someones name who isn't me. They do not delete me from the list, they simply call me from a different number (I block these as they come in) later. So far I have received a couple of dozen calls in the last year.

called twice on a saturday morning and lunch. after reading these posts it’s now just blocked.
