Called me twice with one minute difference ... no message left

They said they were calling for some vacation contest I entered....
The call was disconnected when I said I dont recall entering any contest.

Just called my mobile and didn't leave a message.

Same thing that happened to Sara happened to me. Be careful.

A man called my cell from this number and said that I won a contest from shoppers drug mart and I haven't entered a contest.  He was very rude.   I said he can leave the message on my voice mail he said no and said he will call back my land line at 7 pm.  I don't have a  land line.  I think he is a telemarketer.
