[Resolved]  Idea Cellular — sim allocated to some other customer without even informing

Address:

Nainital, Uttarakhand, 263001

I gifted a mobile phone to my mother with an idea sim |mobile number [protected]| around 7 years back. When ever i called her on this number she never picked up and said i never called. Same was the case with other relatives of mine. I contacted the customer care and they said it is now allotted to someone else. I am surprised that how can my number be allocated to someone else without proper notice. I am very unhappy with idea 's service here. Bank account, whats app and many other important work related services were linked with the number.
Mobile number has become an identity now days
This is very irresponsible behavior by idea!!!
