Vodacoms Clueless accounts department

I salary gets paid in late, so last month my debit order bounced on the 1st. Before month end I phoned Vodacom to ask them change my debit order date to the 7th to avoid this happening again. She couldnt communicate with me properly and said she needed to breathe first and just put me on hold to take a break! After I put the phone down, she immediately blocked my line amd I was unable to use my phone at all. After speaking to at least 6 different people from Vodacom, nobody could help me. They just insisted my account was in arrears and its blocked and I need to pay. Why will the block my line a day BEFORE my debit order was due to go off my account?? The last person I spoke to was so rude, she told me I must just go pay because there is no debit order linked to my vodacom account and I should pay cash R780. I was so fed up but no one can help me to unlock my phone, so I went yesterday morning to pay. After 5 hours my phone was unlocked. Now this morning the NON EXISTENT debit order DID go off my account and there is no money yet, which means Vodacom expects me to still pay R100 penalty for the NON EXISTENT debit order which is going to bounce today because they still tried to take off R780 which they have already FORCED me to pay so I can use my phone. I have 3 small kids at home and then the block my phone 1 day ahead before my debit order was supposed to go off. The accounts department is so rude and not 1 single person tries to help you or listen to your problem. No use for me even trying to phone them now. Its like they had one sentence to rehe**** and each one there sticks to their rehe****d sentence. I want to cancel Vodacom and my hisband want ro cancel his 5 lines with Vodacom as well, please. So will Vodacom pay my penalty fees for bank charges on my bank account after deducting their NON EXISTANT debit order from my empty bank account? No they dont care.
