CONTRACT CANCELLATION NOT FOLLOWED THROUGH!!

This is my last resort because i am sick of waiting and following up. Its waste of my time! Firstly, i had been paying for 2 contract numbers which expired LONG ago and only found out about this in April where i requested that BOTH numbers be cancelled. At the end of May (had to give a calendar month notice to cancel which i was happy with) i received an email to confirm that 1 number had been cancelled which infuriates me as i repeatedly confirmed that both numbers had been cancelled with him. I then called again on 31st May querying this and asked the lady i spoke to to please escalate the matter as all calls are RECORDED and asked for the call to be listened to to prove that i asked for both to be cancelled. She said they would call me in 2-3 days.....still nothing. I called again on 20th June to follow this up as i told her i do not want to pay for the contract at the end of this month as this should have been cancelled. She assured me that she had escalated this again and i would be contacted in 2-3 days.... Guess what???? I am still WAITING and i will need to pay my account in 3 days. PLEASE CAN SOMEONE LISTEN TO THE INITAL CALL ON 21ST APRIL TO CONFIRM THAT I REQUESTED BOTH NUMBERS ARE CANCELED AND GET BACK TO ME!! I am sick and tired of following up because people dont do their job properly the first time!!! Somebody needs to attend to this today and rectify it.
