Cancelled contracts - not done

I requested Vodacom to cancel my contracts on 3 nr's - ***, *** and ***. I got only two retention quotes - one on *** which was an amount of R352.39 - I paid it with eft and emailed proof. I received one on *** which was an amount of R1967.32 - still this contract has not been cancelled. It even shows an arrear amount of R1467 on my account which is impossible. I paid the R1789.83 plus R177.49 to cancel this contract as per Vodacoms retention contract - Still not being done and still shows me R1467 in arrears. My other nr the contract already expired in Jan 2016 - I even asked them give me then a Retention amount so that this contract can also be cancelled - no one email back not a call. I am up to my neck with the back reception in Heilbron - for one total week we could hardly phone - sms - or connect to the internet. I have to pay for services I do not have. I also emailed proof of payments no feedback - I want all 3 contracts cancelled and requested the nr's to stay on prepaid available. No email no call
