বর্ণনা :The land line phone of my home, under Khilgaon exchange-Dhaka, was out of order for couple of days in this month.My phone number was 7211700. Yesterday I found that my phone number has been changed to 47211700.I found this change when I rang to my mobile phone.The change of number was not informed to me by any means.Even it was not announced by the telephone exchange to public whether this change will happen shortly. Another most important issue is that my telephone connection was with ISD facility but after changing the number to 47211700 from 7211700, now I can not make any international out going call from my newly given number 47211700. In this situation, I like to request to give ISD facility to my new number 47211700 so that I can make international out going call.
