Telkom's violation of customer CPA product info rights responsible for account arrears

Locked out from service & account spuriously handed over for collection whilst Telkom is unable to provide proof of having provide statements and product package info since inception of arbitrary conversion from landline to cordless units. The lack of statements and subsequent premium increase info led my account to be in arrears as I diligently paid the verbally advised R199 monthly package premium from cordless installation. Interestingly Telkom continues to receive the monthly premium via eft despite the account being in 'collection' status and the service remaining 'locked out'?
