Declined contract over R34 of balance of payment on cancelled contract

My new application for a contract at Game stores King Williams town was declined today, because of some balance if payment of R35 from my previously cancelled contract of over 4 years ago. Before today, Vodacom made no attempt to inform me of this, no SMS, no email nor snail mail. Despite having access to my account, no debit if such an amount was effected. Yet when I called in to complain about it, I was sent from pillar to post.I spoke to no less than 4 contact agents and only a certain Nonhlanhla was sympathetic. At the end of the day, I'm without a new contract and will probably miss out on the R40000 Game shopping voucher that comes with it.
