MTN *****s my Airtime and changes my package unilaterally

<p> MTN *****ing has ****** my airtime worth R982.36. On 20 May 2017, I took a screen grab showing Expiry Airtime: R982.36, Recurring Airtime: R284.01. On the 21 May 2017, the screen grab showed exact same information as I had not made any calls. However, on 22 May the screen grab I took only showed Recurring Airtime: R1084.01. On 22 April, they changed my Package to call South Africa only when I had requested that the new package after my contract period ended must still allow me to make all calls including international ones. Despite more than 3 calls to 808 and visiting Morningside MTN Service Centre 3 times I am nowhere near getting resolution to this matter. I have screen grabs of 21 May and 22 May 2017. MTN contact centre people are ***********, lack empathy and are totally unresponsive.</p>
