NO CLUE WHO MUST DO WHAT

I HAVE A CONTRACT PHONE AND PHONE IN TO CANCELLED THE CONTRACT. IT EXPIRED ON THE 3 MAY 2016 SO I PHONE IN ON TEH 29/03/2016 REF *** TO CANCELLED IT. TODAY 31/03/16 I PHONE IN AND I AM SEND FROM PILLAR TO POST AND THEY DONT EVEN SPEAK NICE LIKE I AM A PAIN TO PHONE IN. I AM A CLIENT. THE REASON WHY I PHONE IS BECAUSE MY PHONE IS OFF NOW THEY SAID YES THAT IS PART OF HOW ITS WORKING AND THE OTHER ONE SAID I DONT KNOW HANG ON. IF THIS IS THE WAY I AS A CUSTOMER IS TREATED AT VODACOM THEN I WILL CANCELLED ALL MY OTHER 4 CONTRACT AT VODACOM AND GO SOMEWHERE ELSE WHERE I AM TREATED AS A CLIENT. PLEASE SORT THIS MESS OUT AND PHONE ME BACK. THANKS
