One unknown lady came near me in the market and requested me to make a call from my phone. She dialed no. 18003157010 and a sms with a unicode was received. She copied it and she repeated it with another person also in the same shop. I couldn't understand why she did so. I am afraid that she seems to be involved in cyber crime movements and most probably has hacked my phone no. Please take action against such persons and this no. 18003157010 bearer.
