VODACOM NEEDS MONEY

2 days ago I called vodacom to complain charges as everytime they submit the bank reject the debit order. They then charge mee R100 for the rejection even if there was sufficient funds as I went to 4ways branch to show that is the facts. The logged a request for the R100 to be reversed but it was never done and I asked the agent to please change my debit order to eft/cash as this is costing me R7 with my bank in charges and another R100 with them, sowaar they debit my account again. This is not acceptable as it looks like VODACOM needs money and the try to get that from clients in a bad way. I will not pay this data line untill all charges are reversed and I get a amended account not via a sms as my phone cannot open that app. I also asked for them to send the account to my email. Not yet received a amended account.
