Rude, uncouth consultant

Just signed up online for a new fibre package. Yesterday pre installation was done by the installer and they recommended Afrihost as having better coverage and speeda. So i cancelled my order with my isp and this morning have spent the last 2 hours either calling afrihost and signing up online. I just got emals from afrihost confirming my order. So i decided to call in again because i was confused by one if the emials that seemed to suggest that afrihost will be calling the installer to do a pre insgtallation. I chose migration not new installation. So i first got through to a lady who answered but then couldn't seem to hear me yet i coud hear her children playing in the background. Frustrated! I put the phone down and dialled again and got through to a man. So i procedd to tell him about the email i received. And he went on to explain that the installer has to come out to see if the line is active. I interrupted him to t3ll him that the installer just installed a new line yesterday. At that moment he just interrupted what I was saying screamed at me. I was so shocked I didnt even hear what he was interjecting about. I was livid and screamed back at hm asking him who did he think he was talking to a new cstomer like that. He proceeded to continue raising his voice at me telling me he is trying to explain. Then when I asked him to be transfered to a manger he said he is working remotely and couldnt So then I asked for his name and the line went quiet . I looked down at my phone and could see that the call was not disconnected, he just chose to just ignore me. I put the phone down absolutley angy and have since been trying to call management. But there is no way to get hold of anyone that gives an damn. I would like this addressed. I would hate to cancel this whole contract because of one rude employee but i need this situaion to be acknowledged and sorted out. I was so shocked that that guy could dare to raise his voice to someone that told him they just sifned up for a new package. No understanding of how to treat customers. I normally record all my calls but i was having problems with consultants hearing me so I cancelled the call record. I wish i could have saved it so that you could hear how that degenerate spoke to me.
