Bad and unprofessional customer service

I had a bad customer service as I ask the lady who doesn't have a name badge at telkom clear water mall to keep my mother's prepaid cellphone number on the contract that I open with telkom online consultant over the phone. Instead the consultant at telkom clear water mall canceled my mum's number and gave me the new one and to show that she was not professional she never paid attention to what I want but to her colleagues busy chatting with them while assisting me
