Bad service

I have a great concern. My vumatel was disconnected because i totally forgot to transfer the funds from my saving anyway i ask my daughter to make the payment with her card. I logged into my customs zone which is profile for my fibre made the payment and later released the someone else details is showing on my profile. I am concern about this don't they comply to the POPI ACT and this falls under GDPR. I went online and had a online chat and i was told the payment is not showing after i send a screenshot of the payment pending. I explained to the agent on whatsapp what has happened and that the payment went to someone else account and i did not understand what has happen. I was told the funds is showing failed on the name of Ralton Brown i don't know who this person is and how his details show under my profile. I asked webafrica to transfer the money to my account i was told they cant i need to call the bank. My daughter had a online chat with her bank and they advice we need a authorization letter so they can reverse the funds. I have been on the chat again to web africa and was told they cant give it to me. I ask a manager and then the person said no managers available then i said i will wait and then she end the chat. I am still disconnected and i am struggling to get my money back
