After recieving many call from this number I have tried to return the call, only to be placed on a answering machine for several hours. Hope they know I am paying for the return call and if it is a marketing ploy I will seek to charge them for the wasted time.

I get several calls from this number a day and they don't leave a message. I'd say its one of those telemarketing groups...?

Found out who is calling... MelbourneIT call centre.

Keep getting calls from this number and when I answer there is no one there
