Airtime and data vanished

Hi

Vodacom I would like you to refund me my R54.74 airtime and 1 gig data. Yesterday I purchased an hour gig with you guys at 23:52 and my airtime was at R54.74 from R66.74 after the purchase, and the was one episode remaining to be downloaded and mind you the episode was less than 70mb. So when it stopped downloading I assumed it to be the network, forever poor, but a few minutes I decided to check my balances, I normally sent myself detailed balances for proof as well, I did the same when I purchased the one gig and got confirmation and now my balances we're at R0.00 even no data. The horror, even if your network was as fast as Telling and Cell C at 00:16 from 23:52 my data and airtime couldn't have depleted, worse you send us Everytime your data is less then 501,200,50,20mb, and your data is depleted. There was no such, there couldn't be such because the series was just below 70Mb. It's ridiculously annoying, given that you did it as well last month and I let it slide, now it's seems like it's becoming a pattern. I have sent you an inbox on Facebook and not only have u not responded to my query, you also failed to acknowledge the receipt of the complaint, for such a big global company it's appalling. I am on my flexi 111 contract, please I am being very civil at the moment, I demand my airtime and data back.
