Vodacom bad service

<p>On 23/12/2016 I app**** online for an upgrade on my existing contract. I wanted a tablet to be added. I received an e-mail the 24th stating that someone would contact me within 24 hours and if nobody does I must phone a certain number. I've tried several times on various days to get hold of someone to assist me without any luck. I feel this is terrible service. I've been with Vodacom since 1998 but now feel I will consider leaving them.</p>
