Standard bank is useless. And i need assistance

Some company or dealer has been removing money from my account I have requested for this amount on multiple occasions to be reversed. they reverse the amount and then the amount keeps coming off again. My private banker Yola Ngqongwa is unable to give me any answers from the investigation that standard bank was supposed to conduct on the 7th of August and the amount keeps coming off of my account even though they reversed the amount. it has again come off my account 7 days later after reversal. I current performance i would not recommend standard Bank to anyone.
