Agree 100%.
I was impressed when Bafin and Bank of Italy stopped N26 from taking on new customers because of concerns concerns regarding onboarding and AML. These actions forced significant systems and procedural work by N26 and probably made N26's offering a lot better in the long term, notwithstanding the pain/cost they endured. I've had problems with Raisin, Advanzia, BUNQ, Revolut etc with very simple and straightforward transactions that certainly indicate underlying issues with their systems, procedures and staff training and in most cases I've found their support and follow-up to somewhere between poor and awful.
I've no problem with the concept of disruptors/challengers or whatever they want to call themselves this week entering the market, but their operations need to meet a basic standard and they need to be held to account. The Regulators/Central Banks have fallen well behind in this regard and until they proactively police (1) systems and (2) support with the same importance they attach to liquidity, solvency and all the other prudential stuff, then consumers will be at the mercy of these start-ups believing their own marketing hype (bs) and acting like cowboys.
