VODACOM -CONTRACT CANCELLATION NIGHTMARE

In April '20 I made the mistake of ordering a handset on a Flexi 125 plan from Vodacom. What was delivered was 2 sim cards.... no handset. I eventually called their ironically named Customer Care to have the issue sorted out.... it went downhill from there. Red tape decreed that the original (erroneous) contract be cancelled and a new one concluded, however a new one could not be initiated until the original was cancelled.... I will fast forward here to July. After numerous calls to their Call Centre I gave up on a new contract and just wanted to conclude the cancellation of the original one. The agents all agree the cancellation is 'in progress' (for THREE MONTHS) BUT Vodacom persists in **********ly initiating an ever increasing debit order monthly, which I promptly have reversed but it costs me time and money. I am at my wits end.... How can it be so difficult to cancel a contract and stop a debit order that should never have been implemented as the notification of cancellation was made within the prescribed period. No wonder they don't make the contact information for their billing department available.
