You can speak on phone, receiving one from countries killing civilians on purpose is making a statement. If you make a statement you will be heard, and I don't think many EU countries will be happy. Not to mention, you know humanitarian aspects - you can buy your oil without blood.
And, why hasn't the EU shut off all oil and gas purchases from Russia immediately?
Why should a poor country support this sanctions regime and then witness massive internal disruption?
Most of the countries and populations of the world have in fact NOT imposed sanctions.
Because they let themselves get too dependent on foreign energy, so doing so would have meant letting their own people freeze.
