So who will pay my costs

An unfortunate incident happened and really I am a little dissappointed that it has gone this far. Last month my debit order did not go off my account for Vodacom, when I checked the bank sent a message saying the money had not gone off my account, upon enquiry I found out that the bank had made an error and then requested me to ask vodacom to resubmit the debit for payment, the bank then refunded my R90.00 for the returned debit. I called Vodacom I explained to them what happened but the consultant said that payment can only be presented to the bank on the 14th of May there was no talk of additional money so I left the debit amount in the account on the 15th the bank sent me a message saying the debit had been returned again, and charged me another R90.00 when I enquired I discovered that the amount debited on my account was for R100.00 more, I was not informed to have the additional money in my account for the debit to go through. Then I pay the account over the counter, I request my debit order to be stopped and this today Friday, 29th May I went to the bank to pay my account to find that my account is increased by R320.50, when I enquired at Vodacom no one knows.
