Narrative:
Started picking up ice, advised ZTL we needed lower (ice). 'Be another min or so' then we were given 15000 ft (no help) requested lower again. ZTL gave me a heading change only. Now the ice is really collecting. Advised center we need lower now! Dead air, airspeed dropping, controls a little sloppy. Advised ATC to get a supervisor on line now -- we're at the point of an emergency descent. Advised first officer to squawk 7700 when the controller gave me a descent to lower altitude, thus averting a dangerous situation. Center kept telling us how sorry they were. It seems atl would not answer center. No communication in our situation could have been fatal.
