Client service???

My mother is 87 years old. She lives an old age homeI and has minimum monility. I phoned Vodacom today and spoke to George. My mother cannot even remember her own family as I explained to him. She gave him some answers but when I assist he said she needs to give the answers. He then put the phone down in my ears twice in a row. The background noise made it difficult even for me to hear him. I told him I have power of attorney which meant nothing to him. As a client of Vodacom for the past 35 years I AM very disgusted
