SPAM CALLS from DSTV/Multichoice and Agents

DSTV and their agents have unrelentingly harassed my husband prior to his passing. They call up to 5 times a day. Attempts to get them to stop calling and offering new decoders and insurance have fallen on deaf ears. He asked prior to his passing and I have asked several times to stop calling. This is out and out harassment. If it continues I will take action. Its unsolicited and unwanted. When/if I need a new decoder I will purchase one
