Homechoice harassment!!!!!

This company is sooooooo annoying!!!!! They call everyday (at odd hours tooo) , they send messages several times a day and it doesn't matter how many times you tell them to stop calling or ask them to remove your number from their mailing list - is the more you waste your time. I block their number but they use different numbers all the time so I'm always blocking but it doesn't work. I don't know what to do, it's at the point where I literally hate that company and would advise others not to buy from them because once they have your contacts they will harass you!!!!!
