GAME REFUSED TO CLOSE MY ACCOUNT AFTER SETTLEMENT

I have settled the RCS GAME STORE account and on the 26 Feb 2018 i have received the letter that said the account will be closed on the next statement day which is 10 March 2018. I keep on calling customer care and I Am been taken from pillar to post as the account is still not closed and i cannot get confirmation letter that i urgently need to use, account is not closed and all that im getting is the statement. The Funny thing is the AGENTS refused me to speak to any superior or closure departments call ref number ********** 00395 and ********** 0802
