I have a cell No. 9481546535, and from past several months I getting a message from BP-OVRSEA (+55888015) that you have activated a service of Chant Messanger for that Rs 15/- will be charged for 15 days. i.e Rs.30/- for one month.They have written in the SMS. But I found there is no way to unsubscribe this serive. I tried many times to unsubscribe was in vain. Please stop the above unsolicited sms service as soon as possible and kindly redeem my money.
