Contract ended and cancelled, still debits orders going off!!!

<p>I had 2 cell phone contracts with Cell c which ended this year in July. I called in due to previous bad experience to make sure I cancell the contracts myself. I was then informed that the last payment will go off in August. Then in September two debit orders went off again which I reversed and stopped. I then receiver numerous sms's saying I owe and must make payment otherwise my credit record with suffer! MAKE PAYMENT FOR WHAT EXACTLY??? I was on the line yesterday with the cancelations department just to find out only one contract was cancelled? and also that they will make sure both are cancelled and re imburse me for data not used. LOL!! I just received another threatening sms regarding payment. I WANT NOTHING TO DO WITH CELL C EVER AGAIN!!! I will tell all my friends and family not to make use of this terrible service unless they want to end up in this type of nightmare!! I want this sorted out now!!! If my credit score is affected in any way I am taking this to the ombudsman. And I will!!!</p>
