Uninor / Telenor — Internet services not activated

Address:

Visakhapatnam, Andhra Pradesh

I bought a sim 2 days ago. It did activate but is of no use as network is never available and from a day or so there is no network at all to even contact the customer care. Internet services are not activating. I was asked to dial a number but when I did so the reply was 'all your OG services are barred' i don't understand what it means or how to go about the problem. kindly look into the matter as soon as possible! Telenor kindly improve the quality of your services! things like these are a real headache! kindly respond as quick as possible!
Thank you!
