Bike noc cancel

Hello Sir, I took the NOC of my bike from hydrabad to tamilnadu. But I never took the bike to tamilnadu. The NOC got expired. I still have the original NOC with me. Now After four years I sold the bike in hydrabad, but for transfer of ownership the hydrabad RTO is asking me to get a letter from tamilnadu RTO which mentions that my bike was not registered in tamilnadu. I checked with RTO tamilnadu and they are not ready to give any such letter. Moreover tamilnadu RTO is saying that if the bike was registered in tamilnadu then I would have to submit form 28(NOC) to RTO. Since I have the NOC still with me it implies that the bike was never registered anywhere. Kindly help me out in this matter. Regards, Sumit
