Deposits not for me

I have raised my concerns many time with Standard Bank to please investigate the reasons why numerous deposits are being transferred to my bank account. What is even more confusing is why I have to contact my bank actually have to go into a branch and request the depositors details and I have to make contact with whomever is depositing the funds into my account. If I deposit money erroneously I believe I would make the i intial contact however I am always the one who on discovering the funds in my account then have yo get the details of the depositor, then make contact and then transfer the funds back to the person. However these deposits have increased in number and I am no longer going to take responsibility for this. Someone was transferring funds to my account every month I made contact with the bank and it took some time for the bank to send me the depositors details. I then contacted the person who didnt even known that for 5 months the money being transferred from her capitec account to my account was not reaching the intended recipient. The intended recipient also was not aware that they had not received the payments for 5 months. I find this extremely disconcerting like i say despite asking my bank to investigate nothing has ever been done because i have not received a response. I have been seriously inconvenienced and in some instances have spent the money because I have not always been aware of the funds because I dont download a statement often..
