I had a CIM account, was create pre-covid, completely forgot about and never used lol.
I'd seeded it with i think 5,000CHF.
I logged in one day last year and see it was 'negative' but 'positive' - couldn't work out which, because they have some weird set up with CHF/EUR balances.
Anyway i contacted them, and asked what was going on with it, they said i owed 2,000CHF or something in fees.
Thought ok, time to close this, so asked them if i could settle the amount and close the account.
I sent over more funds than necessary, and they said ah you can't send from 'wise' i said, ah ok, well send back and i'll send from HK, it will be a few days.
They said it's fine this time (ok, compliance?) - so they dropped their compliance requirement because they were actually owed the funds.
Then the account was closed, for two months almost no information, no refund of the account balance (1,000EUR or something) - still confused, then all of a sudden after contacting the funds arrived the next day.
Honestly, CIM (Swiss) i understand the compliance requirements, but their UX is horrendous, their account balance system is horrendous, there's no communication outreach (i.e mine was overdrawn from fees for 1+yr), and their fees...
Would give them a wide berth.
Ref this person - they are going really back in time.
