ACR MLG VECTORED INTO WX BY UNCOOPERATIVE APCH CTLR.

Narrative

ENRTE TO DFW; WE WERE CLRED TO PORKS INTXN ON THE SCURRY 9 ARR AND WERE DSNDING FROM FL260 TO 14000'. BECAUSE OF THE EXCELLENT PRESENTATION OF THE FMS; WHICH CAN BE SELECTED TO DISPLAY THE WX RADAR RETURN SUPERIMPOSED OVER OUR RTE; I WAS ABLE TO SEE AN AREA OF WX OVER SEAGO INTXN. THE N END OF THIS LONG; NARROW WX RETURN WAS OVER SEAGO INTXN; AND IT EXTENDED ABOUT 20 MI TO THE S. THE CENTER OF THE BAND PAINTED RED WITH A NARROW YELLOW BORDER AND A LARGER GREEN BORDER. AFTER WE SWITCHED TO FT WORTH CENTER; I DESCRIBED THE WX AND ASKED IF WE COULD DEVIATE APPROX 2 MI N OF SEAGO. I TOLD THEM WE COULD RETURN TO THE SCURRY ARR EITHER AT; OR JUST PAST; GLADD. I THOUGHT AN EARLY NOTIFICATION WOULD HELP ATC. HOWEVER; FT WORTH CENTER EVENTUALLY SAID HE COULDN'T WORK IT OUT AND SWITCHED US TO APCH CTL; WITH THE SUGGESTION THAT WE ASK THEM. AFTER SWITCHING TO APCH CTL; I REPEATED MY REQUEST. HOWEVER; APCH GAVE US A VECTOR TO 220 DEGS AND A DSCNT TO 5000'. I THEN TOLD APCH THAT THE VECTOR WOULD TAKE US THROUGH THE CENTER OF THE WX AND AGAIN ASKED TO DEVIATE. THE APCH CTLR ASKED AN ACR B FLT HOW HIS RIDE HAD BEEN AND TOLD US THAT THE PREVIOUS FLT HAD EXPERIENCED A SMOOTH RIDE. I INFORMED HIM THAT WE WERE SHOWING A MAGENTA RETURN ON OUR RADAR INDICATING SEVERE WX AND THAT WE DID NOT WANT TO FLY THROUGH IT. THE CTLR IGNORED US; AND STATED ANGRILY THAT HE WAS ONLY GOING TO TALK TO FLT XXXX. HE LEFT NO BREAKS IN XMISSION; AND IT WAS IMPOSSIBLE TO COM WITH HIM IN TIME TO AVOID THE WX. THIS CTLR'S REFUSAL TO TALK TO US LEFT ME WITH 3 UNSATISFACTORY OPTIONS: I INITIALLY CONSIDERED SQUAWKING EMER AND TURNING; HOWEVER TURNING N WOULD HAVE TAKEN US INTO THE SCURRY ARR AND TURNING S COULD HAVE BEEN EQUALLY DANGEROUS AROUND BUSY DFW. VIS WAS 0. WITH ONLY SECS TO MAKE A DECISION; DESPITE ALL MY EFFORTS TO COM EARLY; I ELECTED TO PENETRATE THE WX ON THE STRENGTH OF THE PREVIOUS FLT SOMEWHERE AHEAD AT AN UNKNOWN ALT. FORTUNATELY; WE ENCOUNTERED ONLY LIGHT TURB. I AM USED TO PROFESSIONAL; COOPERATIVE AIR TFC CTLRS. I AM QUITE CONCERNED AT THE ANGRY ATTITUDE AND THE REFUSAL OF THIS CTLR TO TALK TO US. I EXPRESSED MY CONCERNS QUITE EARLY; HOWEVER I WAS LEFT WITH 3 UNACCEPTABLE OPTIONS WHICH ENDANGERED MY PAX AND CREW.
