Anybody using Tata Docomo in Mumbai who has successfully registered a SPAM complaint on SMS? So far I have been unsuccessful. I have sent the SMS in the required format: "COMP TEL NO XXXXXXXXXX;25/09/12;13:23;SPAM message" to 1909. I get a reply from 1909 "Your request received."But after this I get a generic SMS from Docomo stating: "For a detailed list of keywords, SMS the following to 121. For bill and duplicate bill HELP BILL,for Value Added services like call conference, Call..contd Me tunes, etc. HELP VAS, for credit limit CL, to activate Do Not Disturb service START DND, to deactivate STOP DND to 1909. Please call 121 for help. TATA Docomo"Looks like they are avoiding registering complaints. Or is it just me?? Thanks for responding!
