Calling from a travel agency , offer cheap package

I live in Vancouver Canada and this number has been calling me almost everyday trying to sell me things or tells me that I won a vacation and trys to ask for personal information. This is not the only number that calls. I have three different Michigan numbers calling me taking up all of the space in my voice mail box with pre-recorded messages. Even upon changing my phone number I am still getting calls from them. I am beyond annoyed with this.

I receive calls from many different numbers.I have decided not to answer any of them unless I know who it is.

receiving calls from 231-732-2056. caller id indicates north star.
