I'm similarly disappointed.

I transferred money to their account about three month ago and still they tell that they cannot find any reference.

I sent them reference numbers and screenshots, then it takes them two weeks to responds: Sorry we cannot trace your transaction, I double check, I send it again, they ask again, ... the same game.

I am a kind of sad, because, I think that those are just some young guys trying honestly to build up a business. However, if they are not able to bookkeep their finances, then this asks for some serious actions.

If there is some collective action, I would be in support of it.

Best Regards
