So asked me to send the registration fee 3k I sent that later on he send me the photos of bike package and documents. And he send courier boy number. Then courier boy asked me to pay 7000 after that he said he it asked me too pay 6999 but I paid 7000 so once again he asked me to pay 6999 so I paid that also .
