Horrible service from FNB bonds division

I app**** for a bond in March 2021. My bond was approved and we just needed to go through with registration. Later it was found out that the seller owed the municipality **** and the registration couldn’t go through it’s been a back and forth since then 7months later. It was found out that the owner hasn’t been paying the bank even though we’ve been paying occupational rent and now we have found out that the property will be going on auction on the 12th of November, I am staying on this property I’ve spent so much on this property,there is still a signed offer on this house it has not been canceled but now the house is going on auction?? What am I supposed to do now my family stays on this property. I’ve tried to contact FNB I’ve spoken to the lawyers representing the bank they say they cannot help me, they escalated the query to Andre Erasmus in the FNB bond division and he just says he cannot help us! What kind of service is this from FNB, all we want is to be able to purchase our house that we now stay in before it gets auctioned and they just choose to turn a blind eye. I have been an FNB client for years my first account was opened with FNB and this is the thanks I get. I would not recommend FNB if you are applying for a bond rather go elsewhere!! Extremely disappointed!
