UNAUTHORISED DEBIT ORDERS

I just opened an investment and authorised the deduction of a lump sum from a specific account. There were issues with the debtor order, so I was told to pay an amount directly, which was done. To my surprise, the lump sum was debited from my personal account, without any authorisation. Stanlib has not bothered to respond to my emails in which I requested a refund. I cannot pay my child's school fees or afford food, but Stanlib apparently doesn't care that they have placed my minor child and I in a dire financial position due to their sheer incompetence. ********ly took my money, but refuses to assist.
