We lost our dream home due to incompetence

I am a Liberty Life staff member and because of that I am able to enjoy bank benefits - 6.75% on a home loan. I thought this was the best news ever as a young couple and this being our first application. Boy were we sadly mistaken!We went to the Hyde Park branch on the 28th of February 2015, where we were assisted with the our home loan application. We had to keep following up with Standard Banks' contact centre. Our loan had been granted a week later. No one had contacted us with this regard, no one had made a call to confirm what the terms and conditions were or forwarded any documentation to us. We had to phone the contact centre in order to get all the information.We then learnt our loan was granted for a lesser amount, we also weren't informed that the loan amount was granted for only 90%. I was then told to send a comparable for the value of the property. I sent supporting documentation on the 7th of March 2015. A case was opened for my request, due on the 13th of March 2015. When I followed up again I was then told I now needed two comparables not one. We still havent received feedback and as a result we have lost the house because another offer was accepted
