Well done on ruining my credit score!!!

So angry right now. Signed a letter that my broker can cancel my policy, but they need to speak to me to do so. only to be called a week later. (and i called in too). was advised that my debits already lodged (which wouldn't have happen if they called me a week earlier) but i said its fine, they can refund me. the consultant said that they will call me then on the 31/10 to finalize my cancellation cause they cant do it before the debits are through (ok, first place which systems are blocked when debit runs happen). NO ONE CALLED ME TO DATE!! got a sms on 06/11 that say that they will try and debit my account again???? i called that number on the sms 3 time and NO ONE ANSWERS (holding for 6min+) now the debit bounced and my credit score is up to **** !!!!
