Narrative:

At cruise altitude FL250, autoplt on, 30 mi southwest of sby VOR going direct to sby as cleared by ZDC on frequency 125.82. Had traffic alert from TCASII at 2 O'clock position and 1000 ft below and climbing. Frequency was congested and we looked for traffic visually. WX was clear. We then had an RA to climb for that traffic and I disengaged the autoplt and initiated a climb. At the same time we spotted traffic as I was in a climb. At about FL252.5 we had another TCASII RA for traffic above us 12 O'clock position and less than 1000 ft. TCASII said to monitor vertical speed so I began to level off at FL253. We had 2 RA's -- the one below we estimate at 300 ft vertically and less than 1 mi. The other aircraft above we estimate at 700 ft and overhead. At no time did we get any traffic alerts from ATC. We tried to let them know that we were responding to an RA, but another aircraft responded first about their RA response. I queried ATC about the incident once clear of traffic. He stated that the incident would be looked into and apologized that was the extent of the incident. I contacted my chief pilot and advised him of the situation.
