Bond Application :(

My wife and i successfully app**** for a Bond on our very first home, which was approved with 100% payout. We then made arrangements to move out of our rental property to the new home and pay occupational rent. On bond registration FNB then changed the Bond value to 90% which then forced us to look for the 10% deposit. However we were refused occupation because of the new conditions by FNB. We then had no place to go and had to pay rent where currently reside to avoid being kicked out. FNB then went on to debit an account that did not belong to us for a separate loan , upon this debit order bounce FNB then reviewed the bond and declined it all together. WHAT A BANK, Completely disappointed, Completely shattered and to think i switched banks from Standard Bank to FNB ... I really regret this decision!!!!
