Shocking Response

We app**** for a home loan from ABSA 2 years ago, we signed a final grant from them for a certain amount but did not take all the money at the time, now after 2 years, we wanted to use the balance of the money and we realised a lower amount was registered than the amount we signed and agreed on. We then decided the only option was to take out a second bond for the amount we needed (the balance we did not use back then), now all of a sudden (after two salary increases) we do not earn enough, but the amounts we want add up to exactly the same as what they were prepared to give us 2 years ago ??? No one at ABSA contacted me for a list of our expenses, they just advised us via the bond originator that we can not afford it ? Somewhere, someone is not qualified to use a calculator or they simply can not read ?
