******* Blacklisting after Vodacom *******ly changes banking details!!!

I cancelled my month to month contract in December after a few months of fighting with Vodacom. After years of no hassle with my debit orders Vodacom changed my banking details at their own accord to a bank account that does not exist which is *******!! Therefor my debit orders returned NOT due to my fault but due to Vodacom's Negligence and ******* practice!!!! I had no knowledge of this change!!!! To make matters worse after my cancellation and paying up my account I get billed and blacklisted for R55. I HAVE ABSOLUTELY NO CORRESPONDENCE REGARDING THIS. VODACOM UP UNTIL TODAY HAS NOT INFORMED ME OF MY ACCOUNT BEING IN ARREARS FOR R55!!! It is ******* to blacklist someone without informing them of said execution. It is Vodacom who is in the wrong not me!!! I have never defaulted on any account in my life!!! I want my name to be removed off off ITC!!!!!!!!! TO MAKE MATTERS EVEN TEN TIMES WORSE, emails are sent to my husbands email address, and on the system its my address!!! What the hell is going on Vodacom!!!!!!! You seem to change particulars as you go along without customers knowledge!!!!!!
