RN594359442GB this package hasn't moved since 26/10/22, say it is awaiting payment of taxes but my customer hasn't been notified and waiting to hear what needs to be paid. Why haven't they been contacted?

The tracking update says waiting for customer fees payment, but my receiver in China cannot pay or doesn't have a link to pay. Can I add their phone number to the order so they can pay the taxes? They do not have any information to pay the taxes. How can we get this sorted?

Hello, i am returning a parcel from Aliexpress to the address given to me. Tracking number - RC500087558UA . The parcel reached the city of Guangzhou where it has already been waiting for 10 days for taxes to be paid, but I was not notified about how to pay them and what the amount should be. Should I pay for this or the person to whom I sent the parcel?
