Annoying Companues "partnered" with Discovery

It's kinda annoying that I get calls from Companies "partnered" with Discovery to offer me products or services that I already have with you guys!! When I say I already have it with Discovery they say they can save me money. Do you guys want companies to take your clients? Just spoke to another "partnered" company to offer a financial adviser to help me look for cheaper products. When I said I already have all my stuff with discovery they said it will only be a call from a financial adviser nothing more. She then said they need information from me, I rep**** Discovery has my info. she then rep**** saying Discovery only give them cell numbers nothing else. How do I get you guys to stop selling my info to other companies? Do you want my first born son or a goat sacrifice? Please tell me so I can get it done! I've never had a problem with Discovery but the calls from "partnered" companies is getting a little too much.
