In this case you will need to submit a support ticket. You must also have access to the email address you used to sign up for your Mumbai Hosting Account.
If you have changed your hosting account password since getting the hosting account, we can either provide you with a new password you specify, or reset your old original one. This is because passwords are one-way encrypted and if you changed it, even we can’t pull up the new password. If you need to reset your hosting account password, submit a Support Desk ticket as specified in the previous paragraph.
The welcome email is rather long so some isp’s and spam filters may think it is junk or spam mail. So check your junk folders and/or spam folders if you don’t see the Welcome email after a few minutes.
