Hi I have a very weird problem
I have sent some coins to cryptopia, they have shown there, confirmations started ticking and then..  my confirmations has frozen on mark 16 from 20 and stays there for a two days already

what should I do? Cryptopia's support do not come back to the ticket

here is tx id 6be3d65158551e099e2364ec1b2302ead08c70d211518ef4050006e28421dda8
any advice?
