Continuous disappearance of airtime.

I wish to make a complaint about Vodacom for the last 5 times, every time I have recharged my airtime in order to purchase data, the balance of my airtime just disappears.

This is in spite of the fact of having a 1GB data bundle present and having the opt in option that prevents airtime from being used when data runs out, activated.

Current it seems I am in fact being ****** from and this seems to stem from Vodacom itself, judging by the numerous stories I have read, I know of someone who has had their airtime ****** for years.

This is obviously grossly unfair and ridiculous that Vodacom is seemingly allowed to do this to their customers with impunity and is even more insidious considering the terrible economic situation that the citizens of South Africa find themselves in...
