Bad & unrespectful Service from Webafrica team

Dear Webafrica management. I hope you guys read this and really improve not only your service but the customer service. I have a problem in your Modem settings which i identified with other technicians and with yours after over one hour on the line which he told me he was not able to do it and needed help to do it. He promised to call me in the next day but did not. On 20 Sep 2019 i chatted for over 40 min and nobody was able to call me to help me. I called 3 times and finally spoke to Mr "Sinethemba" (Tatemba) which Put the phone down on my face! Will send the recording so you can see. Called again at 17:45 and Mr Khuboni which also was not so helpful and just left me waiting, hearing all the laugh in the background. This was from 4:40 pm until past 18:00, second tentative after 2 weeks waiting for them to call me back and I still got no help... Can a manager contact me please?
