Lack of customer care

Dear Vodacom I have a contract that needs to be canceled. I am currently residing in overseas. I have contacted Vodacom for assistance in this matter but Due to the fact that I was a victim of ***** and multiple contracts have been opened under my name, I am unable to cancel my contract which is now paid up. I was told that I must physically go into a Vodacom store for assistance. Do you not think that this is highly impossible for me to do? Yet it was so easy for complete strangers to open multiple contracts without even going into a store under my name. So due to the lack of security that you have, I am now struggling with the problem . I have made multiple calls to Vodacom and no one is willing to assist.
