After installing paytm app and after login, it changed all the numbers to "paytm send money to contact" and deleted all number which don't have paytm account associated with it. After uninstalling it deleted all phone contacts and i lost all the recent added contacts. This problem is reported in product forum and app review also but paytm has done nothing about it...
