Return to sender

My transfer to China for my samples has been returned to my bank. The bank in China rejected it because I put 'sample' in the payment description. I now have to resend my $120 (plus charges again) omitting any description.

Copy of their email:-

Thanks much for your understanding.

Do you remember that you have wrotten any aim of sample fee in the invoice of transfer ?

Our bank suggested that you can transfer again but never write any aim for transfer, do you have idea ?

Look forward to your reply.

Confused, you will be.
