BTC Transaction froze

Hello everyone, I sent BTC from my counterwallet BTC address 1K9mqPucbJJWsZP1tLXtomDJZKzYKgNL7q to my bibox exchange account BTC address 13qefKhAfqpzKkLT3AcyVg7uz7hQu3w2HK

24 hours the coins did not appear on the bibox.
in my counterwallet the status of the transaction is «pending» , but in the transaction did not even appear
Can you help me solve the problem?
