Hello.
You sent IPBC without Payment ID.

Please, check this example - this is IPBC transaction with Payment ID
https://explorer.ipbc.io/?hash=ebd2bdae842114cd901b89340d8c1de106eeb31ebf1fec6dd3603f6f26157b66#blockchain_transaction

and here is your transaction:

it is obvious, that yours do not contain the Payment ID.

There is a warning in the deposit form - Payment ID is OBLIGATORY. If you don't specify Payment ID, deposit will not be credited. Unfortunately search and manual crediting without Payment ID is not possible due to IPBC peculiarities. http://prntscr.com/inkd1b

You also didn't follow our requirement to send small transaction first for test purposes.
