Double debit orders and horrible customer service

Received an sms from my bank for more than double the amount my Vodacom bill normally is. Dialled *111# and checked my balances on the cellphone service - I still had talk time, data and sms's left. Phoned their customer care line, waited 23 mins and spoke to Sibu. Also complained that I haven't received a statement in months! Not in the mail or on email. Sibu was unable to assist, because of details on the system. Afterwards tried logging in to their internet self-help service. It stated that my nr was not registered, yet I had gone through the registration process before. Repeated this process and logged in eventually. Internet statement showed normal amounts due for debit order. Sent an email to their customer care. Still awaiting response. HORRIBLE SERVICE!!!
