Hi Seema,
Still I am waiting for your response. Incase you missed my query, I am re-posting it below.
Hi Seema,
Thanks for the reply.
1. I guess, now you have realized that there is some bug in that page ('Change address' button is active though it wont function like that!) and will be corrected soon to avoid any confusion to the users.
2. Also I would like to know - why don't you send email notification than sending an un-reliable SMS for the dispatch details? A reliable notification method will avoid any such 'first delivery attempt failures'.
Regards,
Visakh
