Airtel — c s ravi mobile number portability issue

Address: 560102

I have a jio prepaid mobile and since most of my family members have airtel postpaid, i also wish to port my jio number to airtel. Initially on 02/12/17 visited their customer centre in bangalore hsr layout and per their advises submitted all requisite documents of my wife's parent airtel postpaid number and also her fingerprint impression and generated a upc number valid until 7/12/17 and shared with the concerned executive of that centre. No action and hence spoke to their customer care 121 and lodged a complaint under ref. Bal/56625003 dtd5/12/17. No action and hence again visited their above customer care and due to some technical error per their request we resubmitted all the documentation and fingerprint. Also generated another upc and shared but no action. Complained to their nodal officer under sr 81595387/5.12.17 & again under sr 8177041 dt.10/12/17. Based on their advises visited the same centre and represented and again generated another upc valid until 24/12/17 but still no action until today, ie. 15/12/17 for such a small mobile portability process when trai and govt. Of india legally permit mnp between telecom operators. Can trai or consumer forum intervene as i am now with no phone and plans of either operator and no positive response within specified time frame for action. Whom to be blamed or is it my mobile portability request illegal for airtel. Spoken to so far 25+ executives of airtel and visited 3 centres of airtel, generated 4 upc nos. And got the jio approval for portability but no action. Hence complained to nodal officer desk and appellate desk. No concrete action either positive or negative till date from any of those approached airtel personnel. What best can we do in such an arrogant and lethargic service providers and can theiir airtel promise be trusted.
