WHY MUST I BEG YOU TO DEBIT ME!

PLEASE EXPLAIN TO ME WHY THE HELL IS IT SO DIFFICULT FOR ME TO CHANGE MY BANK DETAILS! I AM BASICALLY BEGGING YOU TO DEBIT ME!!! I HAVE SENT 8 EMAILS WITH CONFIRMATION OF MY BANK DETAILS, THIS HAS BEEN ON GOING SINCE 7 MAY! EVERYTIME I CALL I AM PUT ON HOLD! CURRENTLY I AM ON HOLD FOR 20 DAM MINUTES! THE CONSULTANT TELLS ME THE DEBIT ORDER DIDNT GO OFF! YES!!!!!!!!!!!!! I KNOW BECAUSE I CHANGED BANKS! HOW THE HELL IS IS MY PROBLEM THAT YOU DONT RESPOND! YOU SAID EMAIL THE NEW BANK DETAILS WHICH I DID ON 7 MAY! AND I GOT A REFERENCE NUMBER INCLUDING A RESPONSE SAYING IT HAS BEEN SENT TO ACCOUNTS. ITS THE 25TH AND STILL YOU HAVE NOT CHANGED IT! I HAVE EMAILED TWICE EVERY SINGLE WEEK SINCE THEN ASKING FOR CONFIRMATION AND YET NOTHING!!!!!!!!!!!!!!! ***!
