Standard bank ongoing queries not resolved

I am frustrated and so dissapointed in Standard Bank business banking. In September a transaction wa sduplicated in error and reflected as two amounts which haf come off the account. The lady at Epping branch completed her documents for this to be followed up on. Nothing was done and in October I went to the same branch again and the lady there indicated that the incorrect documemts was completed an redone the process for the duplicated transaction to be reviewed. Nothing done again. Went to back a third time and another person made numerous calls indicating someone would contact me. Its now December. I have had enough of my time and energy in having this issue and reversal done. A second issue I queried in October was credit card costs that was deducted from the cheque account when we do not have a credit card. Standard bank....if you do not make contact with me with solutions we are closing our accounts. I have never had these run arounds and dealing with ***********, unproductive staff. I demand action and an immediate resolution.
