Vodacom service non-existent!

<p>2 months ago I complained to Vodacom that I was doublecharged for my June 2016 cell phone subscription. They sent me an SMS with a reference number. This was the last written response I got. Since then I called Vodacom on may occasions and spoke to various consultants at customer service, accounts and contracts. They assured me I will get a refund. I was also promised they will call me back, nothing happened.Of course to date I did not get this refund!</p> <p>The lack of service is shocking!</p>
