Bill Dispute

Im a highly dissapointed with the service i received from Vodacom. on the 30th of August my debit order for the amount of R118.50 was unsuccessful, i received an email from Vodacom informing that i was in arrears and i was given an option to do a resubmission for the 30th OF SEPTEMBER. When i called into the accounts dept, i spoke to a lady called Sibongile who was highly ***********, she could not explain my bill to me properly. She told me that i owe Vodacom R437. How can i be in arrears for 1 month and then my bill jumps to R437. She told me that her system shows that there was a resub done on the 16th of September which was unsuccessful so i was penalised for that failed debit. WHO AUTHORISED THAT RESUB?????, I did not request for any resub to be done on the 16th as I only get paid at the end of the month. I called the accounts dept again this morning (28/09/15, I spoke to a lady named Precious, she told me that my case was still pending and that I will receive feedback shortly. She promised me that my line will be reactivated in an hour or two, BUT THAT DID NOT HAPPEN.
