Vodacom gives really pathetic service

I wrote a review on behalf of my son who is a Vodacom customer,a few days ago.It was about the fact that hecancelled his old contract on 5June,and then they took the money by debit order again at the 23rd of this month,and they also stopped all his free minutes as well as his data.A guy phoned him and said they will credit him,but up untill today,notbing has been credited.But according to the Vodacom app,Ref:1-**********0739 has been resolved.Meanwhile he has heard nothing from Vodacom again.They must call him only after 4 o clock in the afternoons because he works underground in the mine and does not have his phone with him until that time .His nr is **********.He is Tiaan Habig.

Ps...We have still not hesrd from them!
