*****ulant Insurance Policy

Vodacom is debiting me for an insurance policy I did not have. I've been contacting the insurance division for three weeks now and each time I'm promised that the matter will be escalated but only to find that nothing has actually been done to resolve the issue. Apparently, someone from a store opened this insurance policy on a prepaid number, but I do not have a prepaid number. Although they know all of this, they still have not done anything about it. This is *****! I tried calling their various call centers but all of them throw me from pillar to post, none are able to help me....this is ridiculous.
