money ******

on the 16 november I trasnfered money from my account to my sons account using my cell phone I found out afterwards that the account number is ot my sons but eh cell phone no is correct. I immediatley called capitec I explained what had happened to them they then said i had to wait seven days because I am sharing my cell phone no with someone else! it is now nine days i have been into the brance in Midrand and called them everytime its a different response, I called again today and they tell me they are still investigating. I have spent so much money buyng airtime they say they will call me but they never do no sms nothing!! this is disgusting and unacceptable I have lost R1100 from my account and want my money reveresed
