CONSUMER UNDER DEBT REVIEW HEARS NOTHING FROM VVM!

I am under Debt Review with Octogen (PTY) LTD since 2010. My MTN account was handed over to VVM, since 2010 Octogen's PDA paid this account (which was included under debt review), I have requested on numerous occasions for a paid up letter / updated balance on my account. No one gets back to me and I am struggling to get hold of these people. CAN SOMEONE GET BACK TO ME ASAP!!!!
