Multi choice *********s Installers

I recently took up Mutlichoice on their Explora package for R899 per month. This came with installation. Yippee! The installer then came out and installed the system. Then I get asked to sign a Subscription Agreement Schedule, that contains a lot of my personal details. I object, because I have no dealings with the installer. How does the installer protect my personal information?<br> <br> To be clear, I have no problem reading and acknowledging new T&C's (if I agree). My issue is that I have to pass my details onto a third party.<br> Why was this not done over the phone, when Multichoice was happy to sell me a new decoder? <br> Why am I now being forced to sign a new agreement, only when installing a new decoder? If the T&C's had changed, Multichoice could have approached me at any time to acknowledge the new T&C's. Why wait until the equipment is installed in my home, and the installer is threatening to remove everything?<br> Had I purchased the decoder cash, or even paid for the installation cash, the installer would not care about the agreement schedule. The schedule goes so far as to say that you can fax it to Multichoice. Why then am i threatened to sign it and give it to the install
