Useless and Inaptitude Customer Care

I have two numbers on contract. One of them is registered to my wife's name. Yesterday I wanted to buy data and used the USSD code from HER phone and HER number. The data bundle however was allocated to my phone number. I immediately contacted Customer Care and was told that the charges can not be reversed and that what I explained multiple times can not happen. He insisted that the USSD code asks for a phone number which it doesn't and that it asks if you want to charge credit or debit card - Which it doesn't. Gets allocated to monthly bill. After trying to escalate the complaint to technical I was told that there is no one to escalate to. This is absolute nonsense. After a lengthy battle I asked for a transcript of the conversation and was also denied. I insist on a refund for the purchase that was not allocated to the right number.
