Why call me on my banking number looking for someone else?

Can you please tell me why on earth am i getting call’s everyday on the cellphone thats linked to my bank that they looking for Mr Malefane. I even got an sms threatening that there will be legal actions against me. I am so frustrated as i use this bank to get my salary and for my business. I have already moved my salary to another bank cause i dont understand whats going on. I dont even know who that person is. One more call from Capitec requesting to speak to this person or if i get another sms. I am definitely closing my account and will move my funeral cover elsewhere. So that i feel safe. At this point i dont trust Capitec anymore after so many years of being with them
