iBurst refuse to cancel account

My son and I have been cordial in 5 months to try cancel my iBurst account, all kinds of excuses are given yet they continue taking money off my account. In addition, some Isaac Mosili keeps sending incorrect e mails to me adressed to Matthew Williams about renewing the account!! They have no idea what they are doing.<br> Cancel this account with immediate effect! Stop taking money from my account. I had a great service from iBurst till 5 months ago, there Retention team is incapable of helping on ANY level.
