i am a prepaid customer of tata docomo. i have done special recharge of rs.59 on my mobile no. [protected] on 14/08/11. according to that i am supposed to have call rate 1p/sec to u.s.a, canada. but when i made call to canada, i have been charged standard call rates 11p/sec instead of 1p/sec. i called the customer care and told the problem on 15/08/11. they gave me complaint no. GBL[protected] and to wait till 18/08/11.today on 18/08/11 i received a call related to my complaint. but they could not gave me any sure reason for wrong call charges and told me to wait again. but they didn't call me any more and closed my complaint. i called 198 again. this time they told that this special pack facility is not valid for yukon(canada). even yukon is in canada then why i have been charged more call rates than mentioned. in ads they says call u.s.a, canda at 1p/sec with special pack of rs.59 and on other side they do not mention that special pack is only valid for some special areas in canada. i have been charged 180rs instead of 15rs.please help me.
