Pep Refuses to Delete My Empty Account After 3 Years

I have been trying to close my long-used Pep virtual wallet account for about three years now, but I haven't been able to get anywhere. I want to close my account, but I absolutely cannot connect to customer service, which means I can't get any official action taken.

My registered email address is no longer in use, so I can't process the closure through the app or via email either. Even though my account has a zero balance and no linked cards or automatic payments, I still can't get it closed, and this situation makes me really anxious.

I am requesting that Pep permanently close my account and provide me with clear confirmation once it is done. Furthermore, I want them to acknowledge that as long as my account remains open, any unauthorized use by third parties is entirely Pep's responsibility. I clearly state that I must not be held liable for any transactions or activity conducted using my name.
