Highly Annoyed and Angry.

hello

I am a new contract holder and have had the worst experience ever.... I have never heard of people deducting money 4 days after you receive the phone, then on top of all that i had to pay their unpaid debit orders after me telling them i have changed banking details due to my previous card being ******.... No answer from Vodacom..... 2 months later i get a shocking bill of R803.00 ...i try and query it but still no solution. I then called the call center and they tell me they have no tracks that i have called and tried to change banking details as if i am going mad.. Please if anyone has had this problem please let me know cause i am now seeking legal action against Vodacom.
