Very Rude Consultant

I call capitec to get assistance with the banking app and the lady I spoke to by the name of Whitney before I could even finish explaining she advised that there is nothing she can do I need to go to a branch without even checking if there is an issue on my profile. I called nedbank and standard bank and they sorted out my issue related to login in on the banking app. Whitney has a bad attitude and does not deserve to be working there assisting us. She went further to say I'm not making sense and whatever I say will not make a difference I just need to go to a branch she can even give me a reference number. She kept on saying she can't hear me but she realized I'm getting angry suddenly we were having a conversation and she could now here me. She did not take any details down. I cannot accept such treatment from a person who should serve me
