Vodacom are ******

Yesterday on the 10th February 2019 I bought 500mb data for the number +27 72 ********** of my girlfriend using my absa banking app, money was paid but the data was not credited even though it went through from my bank. Today the 11th I phoned my bank enquiring about it and they confirmed that the transaction went through but when we phone vodacom they are telling us we bought it for a wrong number even though we have a confirmation that we bought for the right number. I feel we are being victimized by vodacom, my girlfriend spend the whole of yesterday without data she was not believing that I bought the data up until I sent her the proof . Vodacom are ******.
