Rude & uncouth call center agents

Today Monday 6 July 2020 at 16:04 I got a call from Sammy Molefe, he is one of the rude employees of MBD amongst others like Thembeka who happens to be a woman and I would not call her a lady because both these individuals they do not have phone etiquette. They lack respect, listening s****s & emotional intelligence among others. It seems like a bunch of people that have not have trained to handle customers & they hired based on how rude they can get and intimidating. With Sammy, he could not speak clearly and when asked him to speak he became angry and dropped the phone on my ear. This after I had told him I was advised by one of his colleagues to send the e-mail to Percy their Manager/Supervisor of which I did on 04/06/2020 to *** and he only read my e-mail on 25/06/2020 at 10:34. They have not been a response since then.
