INCOMPETENCE of Vodacom is mind blowing! CANCEL MY CONTRACT!!!!

I am extremely livid right now as the INCOMPETENCE from Vodacom is absolutely mindblowing! The number in question is *** it is a data line - I requested this number to be cancelled on the 4th of June and it has still NOT BEEN DONE! This is my timeline of calls with Vodacom, and unfortunately do not have reference numbers:4 June - called Cancellations 5x to cancel the number. I was assured it would be cancelled by month end20 June - called cancellations to confirm the cancellation and they assured me as of 1 July it will be prepaid and any data left over in the month of June will be lost.1 July - The contract was NOT cancelled and data loaded. I called THREE times to have it cancelled and was assured it would be cancelled by end of day and a refund allocated to my account. IT WAS NOT DONE8 July - I called cancellations again as the data was still active and no refund showing on my account, the agent had said that the refund would reflect after 14 days, so I could call on the 15th July15 July - I called customer care who said that NO refund has been allocated to my account. She transferred me to cancellations and I had to explain EVERYTHING again! *** is on the old system and she can't help me - THIS IS NOT MY PROBLEM!!! EVERY TIME I call Vodacom they tell me I'm on the old system - WELL THEN LOAD MY DETAILS ON THE NEW SYSTEM!!! I am blown away by the INCOMPETENCE. I need *** to be CANCELLED IMMEDIATELY and a REFUND allocated to my account. I have cancelled my debit order for 1 August as I REFUSE to pay for a contract that I cancelled on 4 June! CANCEL *** IMMEDIATELY.
