My dad bought a house in 1994 from BOE bank for the amount of R200 000 and then BOE was taken over by Nedbank. My dad's been staying in that house and paying for it for the last 21 yrs... and he still owes R281 000. That's IMPOSSIBLE! !!! for the last 2/3 years, we've been trying to sort out this problem, (according to Nedbank my dad took out a second bond which was signed in 2007) which is definitely NOTE the case... we've asked for the proof of the paper work but no ons is willing to help or getting back to us... for 3yrs no one is help my dad!!! How is it possible that after 21yrs of paying, hr owes more on the house than what he bought it for?!?!?!<br> A few weeks ago my dad paid an advanced on the house of R70 000 (not the first time he paid an advance on the house ) and now the money is put in a scope account and he is not allowed the touch the money to pay for the house unless they say so... Nedbank services disgust me and it like they just don't care and are unwilling to help...how can you not have any history on this from 1994??
