Rude call centre agents

My mom received a call from the unlimited call centre. My mom is a pensioner. The consultant who called her was very rude and had no way of speaking. She has no way of addressing people and interigated me when I advised her my mom will not be interested in any of there products. The unlimited staff are very aggressive in their approach to people via their call centre and in mall stands they very pushy and get innocent pensioners to sign up for their products. I tried logging a complaint with them, but got a long sorry story from Matthew. Totally a acceptable.
