After you file

I posted about 5 months ago now and I STILL HAVE NOT received my refund.  I honestly don't know what to do anymore or whom to go to. Still get the same answer every time I call which is 'just be patient' I have been patient for long enough I can't be patient anymore I need to know where and why I haven't received my refund. Of course every time I call the call mysteriously gets disconnected it's beyond frustrating.  I was going to amended but I don't even know what I am suppose to be amending.
