Hi Sabaresh
I just tried to make the payment last night and today morning and faced the same problem as you. Did you find the solution to it? Cuurrently, I'm also going ?????????
I don't even know if there is any helpline or if there is any email address where we can type our assistance queries.
I have the following suggestions to offer but can't try them immediately coz I need to go to institute today after this and submit membership form:
1. Click on goto homepage on the page containing payment gateway link. Scroll down to the end where you will find a tip stateing 'If you face any difficulty while Registering Online, please contact CMII Secretariat - Placements Desk for assistance.' Try that link.
or
2. Try making the payment on a high speed internet connection. I had the upload problem with the photo and I succeeded uploading photo after using high speed connection. So maybe theres a similar problem here too. ICAIs computers probably are getting timed out too soon and can't take messages from low spped connections.
Hope you succeed with these tips.
