Extremely poor service at Vodacom

I am struggling to cancel one of my insurance products through Vodacom. I have called Vodacom Insurance and after 30min waiting on someone to answer my call, the call was disconnected due a emergency incident on Vodacom side. It's extremely frustrating that a valued Vodacom customer have to go through this trouble just to cancel a insurance product. I truly hope that a senior person at Vodacom can read through my complaint on Hello Peter in order to make contact with me and to better their service. I'm extremely unhappy with the extreme poor service of Vodacom.
