Homeless due to Bank Negligence with home loan app

I app**** for a home loan...which is probably my 5th or 6th in my lifetime. Standard Bank approved my loan with a very high percentage interest of 10.7% Having already signed for the sale of my property I had to accept, but asked for a reduction to (9.5% as I was also paying a deposit. Standard Bank refused. In the mean time they had sent the documents through for registration with incorrect property description...that we had to wait two weeks to amend according to their policies. only to have it sent back for the second time with the incorrect property details again...and I am still waiting. I have to move on Friday and we have yet to hear from Standard Bank. I have for three days, left a message on Rita Chamberlain who is the home loans manager's personal line but I am just not important enough to contact. I have dealt with a Eden Fynn...a team leader form Stellenbosch branch too, who has been avoiding me for two weeks. My livelyhood is as stake. I have to pay occupational rent wherever I go...They overcharged me with the interest rate because they knew I was desperate...( are the banks here to help or ruin???) that question remains. I though FNB was bad.
