Open Question: First time buyer help!!!!!!! plssssssss?

Hi all, we are buying our very first home and everything is a mess right now. Here's is the situation: We found a nice house which is in our budget, and the owner says that he wants move out in June 2010, and we are looking to move in somewhere around May 2010. We have everything arranged, like mortgage, deposit and stuff. A friend recommended a mortgage broker , he was very quick at first, but the day we paid him the survey fee, he is just ignoring us! he is out on holidays, never returns our calls. Only way we can reach him is by texting. At the end of every conversation he assures us that everything is going to be done the next day. Then the estate agent calls us saying that we are not serious about buying this property, he thinks we don't even have a mortgage. so this has been going on and on since 2nd april 2010. every one keeps telling us that surveys don't take that long, and should've been done by now. Now the Estate agent called me and said that the Owner of the house is getting nervous and he is taking the property off the market, because the elections are near and he wanted to sell this house before elections. We are renting at the moment and have told our landlord (he's a very nice guy) that we will definitely move out by end of may 2010, i know he can't throw us out but still , word of mouth matters.... anyway wat to do now????????????????????? pls can anyone advise?
