If you have made a payment via Credit / Debit Card / Net Banking / Wallet and still haven't been able to activate the Premium Membership automatically, we recommend you contact us via the help center and let us know the transaction details, so we could look into the issue.
Sometimes some online transactions can get stuck due to technical glitches between websites - payment gateways - banks. We periodically look for such issues and upgrade accounts in backend. However, if your account does not upgrade within 6 hours of payment, we recommend you contact us by clicking on the above link and provide us complete details of the payment done.
Rest assured, we will either upgrade your account or the transaction will get refunded automatically if it doesn't get verified at our end.
