Delhi dp cell

After mailing several times and also calling they do not pick call and still not updated my dp id from around 20 days... They had given me ammendment form which i submitted with required documents but still they dont do it... My large amount divident is pending due to it.. And of which some last date is july 10 after which it will expire.. Its just mental and physical pressure i get by these... Now only 15 days left will they give me divident or not.. And its just because my dp id is not updated ifsc, micr code not updated right thats why..
