Vodacom **********ly upgraded my contract

<p>i received a sms from Vodacom stating that my upgrade had gone through. The thing is - I didn't request any upgrade! So I sent them an affidavit to confirm that I did not request the upgrade so that they can start investigating on their side. They told me this would take 3 days. It's been two weeks now and still no response from Vodacom who are also preventing me from using my own device and contract. In addition , we have to deal with unprofessional and really arrogant call centre staff who have no idea what they are talking about. Vodacom please sort this out or I will cancel all my contracts with you and move to a service provider that will provide better service and who will not **********ly upgrade my contract. </p>
