I got a missed call from you Tuesday morning 13/9/11.

Who are you?

Received a call from this number and they hung up when I answered.  I don't call back unless I have some idea who the person or company is
.

Been getting lots of calls from this number with no message left. I am on the do not call register and would like to get off this person's call list.

Same as above - call back is an auto message for a 'call centre host' and my phone also no call registered.

I have just recieved a call from (02) 8094 4264 Hosted contact centre service, I am also on the do not call register,

I've had 3 calls from this number and several from very similar numbers in the last week. When I answer they hang up straight away, its says it a call centre of some sort when I ring it it getting very annoying.
