Airtel — not able to receive sms / cant receive or dial calls

Address:

Mumbai City, Maharashtra

I have been using the same number for five years; now i am not able to receive sms / frequently can’t receive nor make calls. This has been reported since over 2 weeks, there seems to be no cure. Airtel has changed my sim twice, i am not able to carry out banking work / and have lost credibility with my customers who can’t get in touch with me. There is no one to sort out this except getting calls from call centers speaking like parrots the same sentences with out a solution. Frustration is the only word i can use here..!!!
