var postdata = "ratepleplan&1250&roomtype&254";

That's not valid post data, it has to be like this

var postdata = "ratepleplan=1250&roomtype=254";

You're not sending the write data or sending it in the wrong format, or there is an issue with the data you're sending. You'd need to find out why the remote service is throwing an error. Use a tool like Fiddler to inspect the network call and see if there is a more detailed error in the response you're getting back.
