Constant Harassment and Invasion of Privacy

Multichoice, I have been a customer for ever (heaven knows why). And on top of that, I have always paid monthly via EFT, for obvious reasons. Your telemarketers have caused me to blacklist any Multichoice numbers that persistently call my mobile number on record to harass me to sign a debit order. For personal reasons I never give my work number as a point of contact. I know that Multichoice should not have my work number on record. Today, at 08:22 the first call I received on my work number was from Multichoice, firstly to "discuss my account", to provide them with my ID number, and to coerce me to sign a debit order. Needless to say, I did not provide my ID number, nor do I wish to sign a debit order. Please desist from harassing me on my mobile number, and now at my place of work. If I wanted to sign a debit order and hand all power to Multichoice to deduct whatever amounts they wish, I would have done so many years ago. Get the message .... just stop! Question: where did Multichoice get my work contact number from? I look forward to your explanation.
