change the address property of one of the endpoints and use that in your service URL, it should work; the problem occurring in your case is the similarity of "address" of two endpoints.
<service behaviorconfiguration="Behavior1" name="BeST.Service.Service">
<endpoint>address="web" binding="webHttpBinding" contract="BeST.Service.IService" behaviorConfiguration="EndpBehavior"></endpoint>
<endpoint address="" binding="wsHttpBinding" bindingconfiguration="Binding1">
contract="BeST.Service.IService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseaddresses>
<add baseaddress="http://localhost/" />
</baseaddresses>
</host>
</endpoint></service>
