impossible to change stop order details

After making 6 calls to the following Vodacom call centre numbers 082111 (x2), ***, ***, ***, I am still at a loss as to who to speak to to change stop order details.<br> <br> The Vodacom website states that the correct number to call is 082111 but it is impossible to access a call center operator via this number.<br> <br> Vodacom clearly has no interest in interacting with its customers. <br> <br> I am trying to avoid an outcome where due to Vodacoms poor customer communication channels, our cell phone subscription is cancelled as a result of non payment.<br> <br> Vodacom please make it possible to speak to your clients!!!!
