Bad attitude

I went to Tongaat Capitec Bank to enquirer about an amount deducted from my account and requested to see the manager, i then explained to him he then told me it was a deduction for Capitec loan i have with them , i the asked him why they deducted from my capitec account without my knowledge or them notifying me because the were deducting from my standardbank, he (Tongaat Capitec Manager) said to me they saw that my salary just started to be paid on my capitec account and they don't need permission to deduct from my capitec account but then i told him that i lodge an application for debt review and i was told by Debtcare that they were not suppose to deduct from my account then i requested their branch contact number for the Debt review company to contact him and for my future reference, he then said to me \there is nothing to explain and there is no refund you will get"i then said but i am a capitec account holder i have a right to such information he then said in a rudely way \""i wont give you the number because the is nothing i will say to them and we as capitec have a contract with you (me) not with them\"" he then gave it to me after i refused to leave the branch."""
