OPT OUT!!!!!

OPT OUT!!! Dear Vodacom. I would like to opt out of ALL marketing and sales calls from you and any subsidiaries and any companies that get a commission from selling your products. The harassment from sales calls in the name of Vodacom is unreal. I get several calls per hour. I block the numbers, but they simply keep coming from other numbers. I don't want any calls I didn't ask for. I will renew my contract when I am good and ready. I would like confirmation that my number has been removed from any call lists on all systems and that any companies you may have shared my number with will be informed as well and that you will enforce it.
