PHONE CALLS DON'T STOP

I received multiple phone calls from Standard Bank. This is after I told them that I am not the person in question and that I have had my cellphone number for years. After numerous phone calls (after a Hellopeter review), they told me they will no longer contract me. I am still receiving phone calls. Some are 7 o clock in the morning. PLEASE REMOVE ME FROM YOUR DATABASE. This is NOT acceptable. I don't want a phone call from Standard Bank to apologize, I just want them to NOT phone me.
