[Resolved]  Airtel Prepaid — Signal problem in roaming

Address:

Tamil Nadu

Sir,
I am from Tamil Nadu & using airtel prepaid number (TN circle). But in my screen display, the network is has been shown VODAFONE IN/AIRTEL (In Andhra Pradesh). I have checked with another airtel sim in AP. But in that display, it appears AIRTEL. Manually i searched the available networks in my phone & my friend's phone. My friend's phone detects airtel signal whereas in my phone, AIRTE SIGNAL WAS NOT IN THE AVAILABLE NETWORKS LIST. I have interchanged the sim cards & tried again. Still no change. I surprised when i see this. My prepaid balance was deducted so many times without making outgoing calls & sending sms in roaming. I'd been charged for browsing though i had active GPRS in roaming. 121 customer care is not valid in roaming & i called for AP customer care centre. They told me to call TN customer care centre. I have reached TN service centre by +[protected] & I spoke with the customer service representatives for roaming charges in. I had been charged Rs 1.5/min. Airtel customer care was not helping when I go out of station.

Kindly clarify the following:
1. In airtel sim, why does the vodafone IN signal is crossing?
2. Why does the airtel sim is not getting airtel signal?
3. Why does the airtel signal was not appearing in the list of available networks?
4. How to reach TN customer service centre in roaming?
