Vodacom *****ing consumer money

Let me tell you a story about Vodacom. I log an upgrade. Vodacom delivers 2 phones with 2 new sims. I immediately call vodacom (15 min after delivery). They made a mistake and logged a new contract... now they need to collect these 2 phones and deliver a new package. New package comes, upgrade done...but wait there's more. The 2 phones are still not collected 2 months later. I have given them the days that I was available...nothing...

so, vodacom double charges me for the new line THAT WAS NEVER ACTIVATED and the sims are still in their little sealed packs. I call vodacom yesterday and guess what. The new line was never cancelled (remember this was the new line that was never acivated...) and I will get my refund after they collect the phones... how is this fair??? Now I get an sms stating

"Dear Customer

Please be advised that collection arranged and only after the line is collected we can cancel .

Thank you"

Nobody has called me to make a collection arrangement...

And then right After that another sms that my call has been closed

So, anybody know which regulator I can escalate them to please?
