Nightmare 2nd Bond Application with Standard Bank.

We app**** for a 2nd bond through Standard Bank which has been an absolute nightmare. We disagreed with the valuation performed on our house as since purchase and wanted a revaluation done. Working with my prestige banker Roslyn Schoeman, she tried to assist us to get the documents which the assessor needed to revalue the property. On the same day this request was sent through, I drew documents from the deeds office which showed two houses in our estate with values much higher than ours. Clearly this was not enough as i received another email requesting exactly what i had already sent through, i filled these documents in and sent them through. Still working through my prestige bank and numerous emails later with still no correspondence from the assessor as to what he actually is looking for because clearly documents from the deeds office is not proof enough, i was told by her to call the home loans department. After 40 minutes spent on the phone with the home loans department i received confirmation from Nasrin that all the assessor needed was for me to get two or three properties listed on property 24 or private property to query the revaluation. I then contacted my prestige bank again to find out where i could send this information through as i had found more than 3 listed sales with exact area of our house with land size 2 - 300 squares smaller than ours with values R200 thousand and more than the value given by the assessor and she said she will give my number to the assessor to give me a call. Its now 2 days later AGAIN and i still have not received a call or any progress on the situation. I literally am at loss and do not know what more i can do. Standard Bank is useless. Quick to give you the bond and thereafter a complete joke.
