Well, by using LeuPay or Mistertango or similar "online banks", problems like delayed payments and frozen funds happen very often, so in cases like that it would be much easier to have an actual place where you can go with your lawyer. Stuff like this does not happen often with "real banks" because they know you can show up any moment.
You probably do not have to go to your bank︀ because it is a safe and reliable banks, while people who bank with EMIs often︁ go through hell. Plus, most EMI do not even have phone support, only email and︂ it takes them days to reply when there is an actual problem.
