Narrative:
The occurrence happened while departing runway 24 at the teb airport. We were cleared for the teb 5 departure which we fly on a regular basis from the airport. While leveling at 1500 ft per the teb five departure, the ny departure controller cleared us to turn right to a heading of 280 degrees and maintain 2500 ft. I thought the clearance to maintain 2500 ft was out of the ordinary. The co-pilot read the clearance back to the controller and nothing was said from the controller. While climbing through 2000 ft the ny departure controller told us to maintain 1500 ft as if we were not flying our assigned altitude. We quickly questioned the controller and proceeded to an altitude of 1500 ft. Upon asking the controller if we were cleared to 2500 ft (when commanded to return to 1500 ft) he replied 'negative' (meaning he had not cleared us to 2500 ft). Supplemental information from acn 637870: controller said to maintain 1500 ft. I told him he gave us 2500 ft and he said he did not. I know for sure that he did.

Title: FLT CREW OF FA50 ON TEB DEP FROM RWY 24 ACCEPTS CLRNC TO 2500 FT MSL PRIOR TO 4.5 DME. N90 DEP CTLR DISPUTES HAVING GIVEN SUCH A CLRNC.
Narrative: THE OCCURRENCE HAPPENED WHILE DEPARTING RWY 24 AT THE TEB ARPT. WE WERE CLRED FOR THE TEB 5 DEP WHICH WE FLY ON A REGULAR BASIS FROM THE ARPT. WHILE LEVELING AT 1500 FT PER THE TEB FIVE DEP, THE NY DEP CTLR CLRED US TO TURN R TO A HEADING OF 280 DEGS AND MAINTAIN 2500 FT. I THOUGHT THE CLRNC TO MAINTAIN 2500 FT WAS OUT OF THE ORDINARY. THE CO-PLT READ THE CLRNC BACK TO THE CTLR AND NOTHING WAS SAID FROM THE CTLR. WHILE CLBING THROUGH 2000 FT THE NY DEP CTLR TOLD US TO MAINTAIN 1500 FT AS IF WE WERE NOT FLYING OUR ASSIGNED ALT. WE QUICKLY QUESTIONED THE CTLR AND PROCEEDED TO AN ALT OF 1500 FT. UPON ASKING THE CTLR IF WE WERE CLRED TO 2500 FT (WHEN COMMANDED TO RETURN TO 1500 FT) HE REPLIED 'NEGATIVE' (MEANING HE HAD NOT CLRED US TO 2500 FT). SUPPLEMENTAL INFO FROM ACN 637870: CTLR SAID TO MAINTAIN 1500 FT. I TOLD HIM HE GAVE US 2500 FT AND HE SAID HE DID NOT. I KNOW FOR SURE THAT HE DID.
