It would appear that Coinbase has simply shuttered their customer service for indefinite time, at least for verifications.
They are not to be reached by telephone. I sent a simple support request asking whether they can send my card to a german address instead of letting their API force use of a dutch address on me because I have previously uploaded a dutch driver's license for ID verification.
They responded with rude boilerplate about 'sorry the verifications aren't working right now, sorry you're experiencing difficulty', without even reading my message.
I have since given up hope of personal CS from coinbase, and attempted to upload bunq statements - these attempts failed with the same error message you're encountering.
Coinbase's reputation in my eyes has fallen very sharply from this experience -- and I'm far from the only one -- there are in fact numerous coinbase customers who have a security hold on their transfers and/or account access and are likewise being handed mindless boilerplate leaving them completely powerless to access their funds without a court order against coinbase (difficult/slow in ideal times, a laughable impossibility during corona) - or without simply waiting for weeks/months/years? until coinbase starts respecting their customers and providing basic customer service again. :(
Lastly, this is my first post on Bunq Together. I was shocked to see that the 'Publicly visible Name' as defined in the bunq app is used for both the bunq.me links, and for the Together account. I do not want my name visible on bunq.me , but I thought that had been populated from my 'Legal Name' rather than 'Publicly visible Name'. Upon seeing this I changed the PVN to 'anon', because I can't exactly have my username B-Azure-Wolf showing on bunq.me either. Many people would want no name whatsoever to be shown on bunq.me , because public disclosure of customers' personal information (besides IBAN) in either the 'name' or 'url' of bunq.me, absolutely opens customers up to both fraudulent and to legitimate attempts to collect funds from their accounts behind their backs, through meta-analysis of the public bunq.me information. Likewise there are plenty of people who would want the name visible on bunq.me, but not disclosed on Together. The reverse is true also, but likely more rare. The solution is to: (1) add another seperate name field for customer definition for the bunq.me page, giving an option to omit name entirely (rather than requiring a blank or anon entry) - and (2) to group the 'publicly visible name' and 'together username' (and any additional Together settings) under a 'bunq Together' folder in the app settings, so it's absolutely clear that's where the PVN will be used. And for 'Private Matters'.... are the bunq CSRs going to start seeing me as 'anon' now on their side? (though if so they obviously have the legal name visible elsewhere in their system too). I want my bunq.me page to exist, but be anonymous and therefore immune to meta-analysis. I want to be able to freely define a human readable name for Together. and lastly, I want to be addressed by my legal name by 'Private Matters' (where other users will also want the option to be addressed by a user-defined nickname!) I will pass along this last (giant) paragraph to 'Private Matters' if I haven't gotten a response on this issue from bunq by Thursday 16/4/2020.
Best,
- 'B-azure-wolf' / 'anon'
