Game - POOR CUSTOMER SERVICE

I have been phoning Game Accounts Department since 10 December 2018, and to date had no feedback - or the feedback received useless info . I requested first December 2018 statement in order to make the correct payment, to date still waiting for this. Requested twice the statement for January 2019 to make the required payment, still waiting for Statement. When I tell them I have last received a Statement on 14 Nov 18, they re-send me the November Statement! Do they not understand I want Dec and Jan statements! The staff very rude and unhelpful
