Vodacom are unable to repair a lost data connection when on a voicecall !!!

<p>I complained 9 months ago about losing data connection while on a voicecall. Of course Vodacom had no reference of this so "officially" laid a complaint on 24 October 2016. On Friday 13 January 2017 due to system glitch this problem was marked as resolved. Still no feedback. Vodacom only care when their money is due !!! I have been a loyal customer for over 21 years and feel it is time to cancel my contract and to move on.</p>
