I'm more or less in a similar situation.
I have bought BTC a few times on the LNP2P BOT, using different payment methods. The last time I use for the first time an account from one of the big Spanish banks.
A week later my account was blocked, they said that someone has tried to log into my account and they froze the account for my own safety
Three weeks has passed and I can't access my funds.
I'm lucky because I have some other funds in another bank.
But I don't want to think if this blocked account was my main or only account....
Good luck, I hope everything resolves in your favor!
Finger Cross
I hope to solve it before I run out of fund in the other account.
