bad service

I'm so disappointed with the service at Sunday Times, I April 2015 I subscribed with them to deliver news paper on a daily basis. Since I subscribed I have never received even one news paper but they have been deducting from my account monthly. In May I called in I was promised that they will get back to me. In June i called back again and requested to speak to a superior. I spoke to Joann(Team Leader) whom said since there's no records of me calling them in may they will not be able to refund for the two months that they have deducted from my account. I then asked her to cancel my subscription since I was not receiving the news paper at all. YET THEY STILL CONTINUE TO DEDUCT FROM MY ACCOUNT ON A MONTHLY BASIS. ON THE 2ND OF September 2015 I CALLED JOANN AND SHE PROMISED SOME ONE WILL CALL ME BACK BUT TILL TODAY NO ONE HAS CALLED BACK. I HAVE USED MY OWN AIRTIME TO CALLED THESE PPL BUT THEY HAVE NO DESENSSY TO CALL ME BACK. YET AGAIN THEY WILL CONTINUE TO DEDUCT FROM MY ACCOUNT AND I MUST USE MY OWN MONEY TO CALL THEM BACK. I'M JUST TIRED OF SPEAKING TO THE STUPID JOANN WHOM DOES NOT PUT HER CUSTOMER 1ST. MY *** THIS MATTER NEEDS TO BE RESOLVED URGENTLY.
