VODACOM

So I had a charge go off my airtime, when I checked my billing on vodacom it said it was a Google play charge, which was strange because I never made a purchase for such an amount, and my account uses biometrics for purchases and I haven't got anyone that uses my phone other than myself. On my Google account there in no record of this amount and this so called purchase is not listed anywhere on Google. I checked what I needed to do in order to get a refund from google, which was to fill in a form but in order to proceed with this I need a correlation/transaction ID from my carrier, which is our beloved Vodacom, I have asked and asked and asked for this ID which Google says they don't see at all on their side even of the purchase was visible. Only vodacom can give me this, vodacom is telling me I must contact Google for assistance and they only pick up Application, PK_Google_Sub N which doesn't help e at all because this doesn't even say what application, all I want is for my airtime to be refunded, I have to be able to prove to Google that they took the money and I can't do this because vodacom refuses to help me, or they don't know where to look, or do their job, or are plain lazy or ***********. I feel that this is really outrageous because it doesn't seem like vodacom know what is going on with their own systems because they cannot trace this transaction other than that google application sub thing, they can't say that it was really a Google charge. I just want my airtime back I don't see why I have to pay for something I have no idea what it is or something I didn't purchase myself.
