My account is blocked , cannot contact or reactivate

Hello, I really need some help with my situation on my account being blocked. I am outside Portugal at the moment and I was not able to pay the bills since my Meo wallet does not work when I try to pay online, it does not recognize my details. I reported this issue with them in the past. As I was not in the country I could not opt to pay the bill at an ATM. Now my phone is blocked and also my online account. I simply cannot reach anyone so I can find a way to pay and I don’t know how to sort this out. I would really appreciate any guidance. Thank you.
