My problem still not resolved.. People from airtel technical team call me and tell, "please switch off and on your handset sir, it'll work now, we resolved your issue". But the problem still not resolved. How can I approach to resolve it.

Still not resolved..

I had ported from Vodafone to Airtel postpaid on 15.01.2016 with mobile internet pack, but still I can't access the mobile internet. Complained many times through Mail and customer care, but of no use. I can't attend my online transactions and suffering very much. The represents at Local Airtel store ( Srikakulam, A.P) are also not attending to my problem. My handset is in full working condition.
