Dear Sir
for the last two months i am facing a problem, that few of my people call me from Kerala, to my Mobile No, Idea. but i get the complains from them that this number is going to some one else ,where they are not even known of the language.they asked me to check weather i have diverted the calls. i haven't diverted the number,and i am not able to get these particular numbers. and this wrong number person started making calls to my friend in kerala ,whose number reached to this fellow. this started to happen few months, may be for the last two monts.in month of april and may i was out of station and i was not using this no.i have a doubt weather idea gave my no to some one else also.but then only few people have this problem of call divert. kindly do the needful( my ph no[protected])
