Hey everyone!!
Few days back I filled the conversion form available on ICAI website for converting my registration from cpt to CA foundation and made a payment of 500/- online through paytm. Now to get the study material I need to order the books on ICAI online store for which I need to sign up into my account. But as soon as I enter the required details as asked (registration number and DOB) ,it show 'invalid entries ' !!!
I even tried to contact ICAI in this matter but all in vain !!
please suggest something /!!
