Openbank Invalidated My Card Without Explaining Why

I am writing to complain about the blocking of my Openbank account and the invalidation of my card, which has left me without access to my own money for daily living expenses. Three days ago I tried to make a transfer from my Openbank account and a message appeared stating that my account was blocked. To understand what was happening, I went to a Santander branch to ask for information, but they only gave me the Openbank customer service phone number. When I left the branch, I attempted to withdraw cash from an ATM, but the operation was not possible because it said that my card was invalid. I then called Openbank, but they did not give me any clear reason why my account had been blocked and my card invalidated, and they are retaining my money, which I need for my family’s food and daily expenses. The last four digits of my account are 9282. In a later contact with customer service, they only provided me with a case reference and told me I would have to wait almost a month to obtain a solution, without explaining the specific reason for the measure taken against my account. I urgently request immediate access to my money and a prompt solution, as this balance is essential for the basic needs and food of my family. I also ask for a clear and transparent explanation of the reasons for blocking my account and invalidating my card, as well as for this situation to be resolved as quickly as possible to avoid further harm.
