Once you send a mail to retreive your user id and password, KEA takes time, Devi. They have a turn around time of 24-48 hours which means they are well within rules by not replying instantly. All you can do at this point in time is to recheck your Email Id Inbox and text messages Inbox to see if there are old messages from KEI regarding your User Id and Password. If you have lost the credentials, unfortunately, there is nothing much that can be done except for waiting for KEA to respond.
