Bad Customer Service Agent

I’m totally appalled by Vodacom call agent staff not all but I spoke to a Mohammed today and the attitude of this guy is just unacceptable. He was so unprofessional I needed two things as their insurance department does not want business I had asked him to assist with a quote. The guy sounded so dodge and now and again he would want to laugh in my ear for no reason and when I addressed the fact, when he eventually asks me for my details in regards to the POPIA act he reckons to me well you the one that called us indeed I did but I then told him your whole attitude is bad wanting to laugh in a customers ear which makes me so uncomfortable. How do Vodacom hire these people that has no sense of customer service? However they work in these departments.
