USELESS VODACOM AS ALWAYS

So today I make a phone call to call center after I made an error of buying data for the wrong number from my cellphone app. I have proof of this transaction. I phone this service provider with the hope of being helped all I got om the consultant is that there is absolutely nothing we can do, it was your mistake. When you deplete our data you are able to do something but when you supposed to help you cant do nothing???? I tried phoning the incorrect number it goes to voicemail, how difficult is it just to go into the account and reverse or at least transfer to my number????????? ESPECIALLY SINCE I HAVE PROOF THAT IM THE ONE WHOHT IT?? YOU HAVE TO BE THE MOST USELESS PEOPLE I HAVE EVER MET!!!!!
