********** upgrade done on my account

i took a contract (account number I***-7 cell no ***) with vodacom in feb 2013 and it was supposed to expire in feb 2015 but it was *****ently upgraded without my approval or consent. i contacted vodacom about this it was reffered to the forensic department in march for investigation. Peter from forensic did a credit note and referred the account to be cancelled to Lesley Dean. Lesley did not respond to my emails and finally when he did he also referred this account to Sindiswa Jentile. Peter came back from leave and he prepared the 2nd credit note but until now my contract is not cancelled. i called the account department i was told i owe and my contract will not be cancelled until i pay. the agent that assisted me logged a call explaining my case REFERENCE S3-82G2V-VKFQ1 and assured me that i must expect a call from vodacom within 7 days. i am tired of calling and not getting any assistence. all i want is my contract to be cancelled permanently and my debit order to be stopped. PLEASE CANCEL MY ACCOUNT AND REMOVE IT FROM THE NETWORK ASAP....
