Terrible service from Vodacom

Vodacom's service has deteriorated drastically, such terrible service and 3 weeks later and my query has not been resolved.

What does on need to do to get a matter resolved.

I bought data via the vodacom app, was charged twice and then when I requested a refund I have been asked to send the relevant documents via email which I did. Then I receive no feedback and I get an sms saying my query has been closed.

Then I try to contact vodacom again to be told by the consultant named Hlulani Mathonsi, that I must send her my proof of payment and that she will follow up with the consultant Candice Major that was handling this query.

This has been going on since the 28th October 2020, it is now the 19 November 2020 and this matter has not been resolved. I received and sms yesterday indicating they are still investigating the cause and will advise shortly of the resolution. 3 weeks later and they still investigating, how long does it take to resolves this.

Highly disappointed and frustrated and will not recommend this network provider to others.
