Vodacom ********** Upgrades on Business account

We filed a complaint for ********** accounts opened and charged to our Business Account. Both these accounts were opened with a false company letter head, a false ID and a false signature (doesn't even resemble our actual letterhead or the signature of our CEO) at Vodashop Four Ways. In December 2018 only some of the money for both these upgrades was refunded to our account. In August 2018 we again filed a ***** complaint - this time for unauthorized upgrades, to two of our existing accounts - apparently both these accounts were upgraded via the phone. The one number is actually just a sim card for our premise's gate and now we have to pay almost R 2000 a month for this so called upgrade for a I Phone X we don't even own. The other one is for a sim card that was blocked - but now we also have to pay for a IPhone X and a Smart L contract also almost R 2000 per month for a phone we don't own and a contract we don't use. Till today - Vodacom has done nothing about it - we cant even cancel the contracts because Vodacom said it was Upgraded so that is just too bad.
