Pathertic staff at Sanlam loan queries

Good day my account (LOAN) is paid up and you received the banking confirmation that the loan was paid up but yet today you decide to debit me again. This is not acceptable at all. Phoning your offices is nightmare as i keep on being transferred from department to department and every time you as Sanlam drop the call and after an hour on the phone this morning i had enough now. Even logging a complaint on your website you dont get a call at all whilst i states you will get a call soon. Dont know what your soon is. Your managers are allways in so called meetings/training the oldest trick in the book when you want to speak to them i had enough and i want my monies back as i did not budget for this to be deducted today from my account at all.
