Reliance Communications — port rejected by reliance 4 times saying upc mismatch

I have reliance gsm postpaid no. [protected] [j&k] since 10 years and now as its services are being stopped i hv requested for upc code and got it. Now as i have got upc code, i hv opted for port but reliance rejected my request 4 times. I have submitted upc within time with proper bill clearance and still reliance is nt accepting my port requuest. I dont understand if reliance itself gives upc then hw cn it reject upc dat too 4 times. I want to retain my number. Nw plz solve my issue urgently
