Airtel — roaming Service not available in Chennai

Address:

Mumbai Suburban, Maharashtra

I have prepaid number from Airtel [protected]. When I travel to Chennai, this number is not in roaming. I have complained to Airtel 4-5 times in Mumbai and in Chennai but they are not helping. Everytime they tell to change mobile, sim or switch off, manual selection. All this has been tried. No wwhenever I call Mumbai helpline, they give execuses that our systems are down, please call us back. This has happened 3-4 time.

Because of this I am unable to use this number while in Chennai and I miss lots of my customer, official calls and can not connect with family. This is the service (to stay connected with family , friends and business associates, while travelling ) for which everyone take mobile , and this very service is not available.
