Vodacom is now effing with my credit rating!!!!!

I had a direct debit set up for the 31st of each month for the amount of R135 to be deducted. For some reason you were unable to deduct this amount in October 2014 (I have checked my statements and there were funds available). I fully understand that paying my account every month is my responsibility, however no one from the Vodacom offices bothered to give me a call or email me when they claimed they were unable to deduct the funds from my account.I called in on Friday and participated in the Vodacom online chat, however that was a complete waste of time!The service was so pathetic that two of the consultants I was chatting too, just ended the chat.I then went into the Vodacom store on Saturday where the consultant that assisted me advised me that Vodacom only attempts to contact customers once via telephone and via email. which is utter nonsense as that is not stipulated in the terms and conditions!to top it all off the record of the one telephone call made and email sent was to an invalid number and an email address that has not existed for the pass 3 years! i have much more to add however this only allows 1200 characters! VODACOM is now messing with my credit rating!!!
