Hi 
a few weeks ago, after buying an apartment in puerto del rosario in 2017, i received a letter "Carta de aviso" from the Agencia Tributaria" where they claim payment for the years 2018/19/20. 
Why they sent this letter after 6 years? why they don't collect the Money as a direct debit from my spanish bank account as we agree at the first payment.
The biggest problem is that I can't connect with the tax agency either by phone, email, twitter or facebook, nobody reply to my messages. 
Do
