Vodacom are *****ing from their own customers

I have been with vodacom for decades and the only network i have ever used. But it came to my attention that whenever in recharge, overnight my airtime is missing. They are so cruel that they even take away your advance airtime after it has been successful. Advance airtimes are there for emergencies but the support from vodacom is poor, they *****ing from us. And i have been reading the reviews, they only attend to matters where they can cover themselves, the rest they not giving any explanation. Since lockdown started i suggest to everyone to see the reviews on all these network companies and make your decision which network is best.
