Welcome Gouri,
Well after reaching the threshold limit then we send you a verification code to your address (this is a one time process) , you need to verify your address by updating your payment details with this verification code.-this process takes 2-3 weeks.
Yes we send your payments through cheque only after verification and reaching minimum limit. It will take around 3-4 weeks depending on the post and distance.
Please update your payment details- remember that you give your payee name same as in your bank. and also this payee name can be updated only once.
Go through the forum topics under HELP section and still have any query please post.
