Paw Paw Wireless is past it's 'Best by date'

Thanks to this business, I will never ever sign up for Clientele. I receive a couple of calls from them on a daily basis. I have tried to blocked them, sent them them many SMS's, ranging from cordial to not-so-cordial. It is harassment and ***ardly, communicating with a recorded message is not an option. Where do I go to from here to get this issue resolved? Clientele, Paw Paw is doing a good job of losing you potential customers and you're probably paying them to do this.
