Cancelling Vodacom today

Vodacom's Customer Care is non-existent. No matter how many calls one makes, issues are not resolved - or one is fobbed off with "someone will get back to you' 1. On 10 Sep 2017, a R149 data bundle purchase was routed to my recycled Sim card. To date I am still awaiting resolution of my request to refund this amount. (Re1- ********** ********** ) 2. On 26 Sep my mobile package underwent a compulsory migration from my Blackberry BIS contract to a Smart M package. Despite several calls to the Customer Care number, no-one was able to resolve the issue so I decided to wait for 1 Oct for the new package to take effect. I have just received my current invoice of over R1,000 ( for last month when the Smart M package shouldn't have been instated) including almost R450 for data services - this, when I don't even use internet, only download emails and make the odd WhatsApp message (not phone call as my device doesn't support calls.) My previous invoices average around R650 so this huge increase is unacceptable. Phone cut off twice making calls to Customer Care so reference number not even received! I am at my wits end with Vodacom's slow, non-existent or nonsensical response to queries. As a loyal contract holder, any allegiance to the Vodacom brand is waning and I am now considering alternatives.
