Constant phone calls and e-mails

Direct TV  877-389-6582  calls every night between 7 an7:45 P.M. Most of the time no one is on the phone. We dropped them several months ago after several attempts to get our bill lowered with no luck.  Since we dropped them, they are constantly calling and e-mailing me offering all kinds of deals.  Have told them many times not to call us.
