Vodacom suspend both of my lines with consulting me

Since day one with Vodacom the contract deal is a nightmare. They do debit orders with double amounts without my concern. Now my account is suspended due to them not following up on my communication I had with them via email and telephonically asking them to firstly, change the debit order date because it's wrong date ... secondly, why is it that every month I am penalised. One of their agents said that the debit order was turned off on their side. It showed that I have to pay cash (but know one informed about that). Now they told me I have to wait until my pay-day to reactivate both of my lines.
