We don’t handle sales ourselves, I have no insight into the actual MyCommerce/ShareIt financial transaction. Some paymant methods aren’t instant though. That’s probably the case for the method you chose. In such a case you would receive an e-mail from MyCommerce once the transaction has been finalized.
The only thing I can see is that your order currently has the status ‘Payment status unknown’. Whether that means it failed or that the money just didn’t reach MyCommerce yet, I can’t tell.
PayPal and credit card purchases are typically best since they are processed instantly.
If you have more detailed questions regarding the MyCommerce transaction, try their shopper support. I can’t see more than the current order status mentioned above unfortunately.
