Unlocking my mobile line

Hi, I cannot believe I am still up trying to get my damn cellular line UNLOCKED! My line was locked due to backlog for September installment, which was paid via EFT yesterday/today. I did this so my line can be unlocked ASAP. Called Vodacom customer care & they offline. How convenient. In same instance, wanted to make sure they cancel my double debit for end of October (Sept+Oct installment )and that ONLY 1 INSTALLMENT FOR OCT will be debited. NOT 2 DEBITS. As I have already paid for Sept via EFT. I need confirmation on this asap as it's a headache trying to get them to refund me. <br> Also, want a 250mb data bundle (that is added to my bill every month) to be cancelled with immediate effect.<br> Can someone please get back to me to assure me of the above?? <br> <br> Mrs R.Davids <br> ***
