DISGUSTED AT THE LEVEL OF SERVICE !!!!!!

Hi, I cannot believe the low level of service I have received from vodacom. I cancelled extra data and airtime on the 1st March at 10am with Vodacom, I kept getting told it was done. Then I keep getting told it had not been removed.....it has taken me 44 calls to Vodacom and I am still not winning. I complained a week ago on Hello Peter and was told that an agent would call me......still NO ONE HAS CONTACTED ME !!!!!! I have now been sitting on the phone the entire morning once again to try and resolve this matter. I have now been told that Vodacom had a systematic problem and nothing has been done that I asked for on the 1st March....it is now the 11th March and I STILL CANNOT GET HOLD OF ANYONE TO HELP ME !!!!! Please can some one of authority call me as I will now cancel all my contracts with Vodacom I am soooo upset !!!
