Arrogant Service from MTN

My fathers phone got ******, he is 73 years old. I phoned MTN to assist as he will not understand nor can he hear very well. I asked MTN to please assist by blocking the sim and place the phone under the blacklist. The operator then said I must phone again when I am with my father as she cannot assist me when I am not close to him he needs to answer a few questions. Were is the humanity??? Does MTN not understand that my father is 73 years old and does not understand all this stuff. But no the operator will rather be arrogant with me and tell me that MTN does not make any outgoing calls. I am so disappointed and would not recommend MTN to anyone. What would it take to for people to get back their humanity and start helping people. Once I get my fathers contract in order I will move him to Vodacom.
