Stopping Re-occurring unauthorized debits

[allisonm]

Hi Community 

I need assistance or guidance regarding debits on an account of an informal association. Standard Bank has dedited the account on a few occassions without authourization, warning and communication with myself as the sole signatory. Amounts like R40'000 and +/- R60'000 recently is nothing to take lightly. Please I need the community to assist me or guide me. They claim that its for a personal homeloan bond account which I held years ago. I have not received any communication regarding this bond account in years. Can they debit the informal associations account for my personal debits and can they just randomly take any amounts whenever they feel like it? Please help as I am loosing my contract with the association? 

Thanks
