I sent a first mail 09 Jan 2021, then a second one 13 Jan 2021.
I got a first reply 14 Jan 2021:
Our team will look into this and get back to you soon. It might take 5-10 working days.
The problem was solved 22/01/2021
Thanks for your patience.
Our tech team checked the transaction and resolved the issue. You can check your COBINHOOD account and retrieve it.
We are sorry for the inconvenience caused.
I think the most important is that they solved the problem, since they closed long time ago.
