Poor service home loan department std bank

I am in a process of buying a house the bond was approved in March , the had a very poor service, when they had to allocate the Attorneys , they kept on referring to Attorney's that were about 500km away from where I am, when you phone them they take their own sweet time to rectify the problem. The developer had now increased the price of the house, I had to run around and ask for extra loans to top up, now we at the registration process they sent the assessors four times but the occupation certificate has already been given to the agency, don't know if this is the how it's supposed to be done? The developer is again trying to cancel the deal because they taking too long to register. Am just so fed up with this , but because I'm in desperate need of the house, and wouldn't want to start all over again with this exhausting process. Please assist.
