Unprofessional service

My debit order always goes off on the last day of each and every month.I did call to check if i qualify for a payment break about 2weeks ago and i am sure i spoke to a guy by the name of Julian,I only enquired and i did mention to him that i will let him know but he activated it without my permission (PLEASE CHECK THE CALL RECORDINGS ON THIS AS ITS CLEARLY STATED THAT ALL CALLS ARE RECORDED).so i noticed my debit order didnt go off yesterday as it normally does.I called the contact centre over 6 times today and was cut off by every person and i had to keep explaining the same issue over and over again and seems no one can assist me.I need urgent assistance as its of no use calling the customer care.
