[muhammad-davatgar]

hello, i am aware that there are other issues similar to this title but i just didn't find any answer in the comments, so i would appreciate it if anyone could help, i need to make a request to this wsdl but i keep getting the error "method or namespace is empty, well , i am passing the method name as first argument to the Call method so i guess it is the namespace ? how can i specify it ? thanks
