Standard bank unable to assist with ********** debit orders and client left to suffer with bank charges!

I have been struggling for 3 months already with debit orders going off on my account on the 25th of every month and on the 1st of every month. The first time the debit orders went through and when I queried this at the bank the assistant actually pointed out that there were sufficient funds but the debit orders returned unpaid after realizing my bank account was in a minus of more than R600. I followed up thereafter to come to a conclusion as to what the bank is going to do about this and then the tellers helping me said they can stop the debit order from going through but they will charge me for every debit order and if the amount or date of the debit order is changed by this ghost company Phone Vault and United Con the debit order will proceed to go through and I will still be charged for the stop. I then called my prestige banking explaining to her i am on the verge of closing my bank account she said i should leave it and if it still goes on for 3 months i should then we can see what to do. Every month my account is in a minus of more than R500 -R700 and I am having to pay these bank charges. Standard bank is supposed to assist their clients where things like this is concerned it is ***** thos small amounts add up and you have no idea how that amount that might seem a small minus to your company becomes a big chunk taken out of someone's salary.
