BSNL — bsnl mnp porting code

i am dp sharma holding my bsnl prepaid mobile number [protected]. i had applied for mobile number portability from bsnl to vodafone accordingly i had forwarded a porting code BX942298 which i received from bsnl. i had submittted all the documents as requested by vodafone, vodafone while processing my request had intimated to me that the porting code bx is being used for karnataka state and hence they were not able to process my case. req bsnl to look into this matter
