United Cellular Call Centre harassment

From as today I keep on getting calls from this company!! Calling me about my cellphone application. Every time I tell them I did not apply. Then I want to know where they got my number from, then they cannot answer me. I ask what is the name given with the application then the caller seems to 'hap babbels' as the name is a ummmmm xhxhxhxhxhxh, now who the hell knows what that means. STOP CALLING ME!!!!!
