unwanted calls about my land line and direct tv
I'm getting calls on my cell phone from someone stating I can get discounts on my att and direct tv account. Of course I don't answer them. They are daily. Somtimes twice a day. It's the same voice. The numbers are different each time and they say to call back to that number.
I'm not an att wireless customer but my land line is and I have direct tv.
Please help me to stop these calls.
