Double debits then reports account to ITC

I have now tirelessly exhausted all other avenues.<br> My account have been double debited on 31 December 2015.<br> My bank account have only allowed 1 debit order to be deducted.<br> The successful debit was refunded on Monday the 04/01/2016. I have tried to contact Vodacom multiple times to report the mistake. Unsuccessful and Vodacom then started to threat to lock my profile(5 Lines), logged late payment to ITC. I have made an transfer to clear the difference but I am unable to receive any support to confirm that my name is cleared and I still receive endless automated calls threatening termination of service.
