False COVID 19 results

I am really hurting that i might have infected that I might have infected my colleagues,my child and other fellow South Africans wth COVID 19.on 15/06/2020 i went to Medicross hospital for Covid test and the results came negative via sms.Myself and my child became close contacts of my spouse who tested positive to Covid 19 and we had to retest on 26/06/2020.on 02/07/2020 results came negative via sms and i recieved 2 sms which i believed that the results are mine and my child's.I phoned Medicross for verification and they told me that the results are mine annd the child's and we are both negative.I had isolated since the 26/06/2020,,so now that the results were negative i went back to work same day 02/07/2020.On 06/07/2020 while i was at work i recieved another sms from Medicross hospital that i am positive.i dropped everything,went home to call them.I called them and spoke to Ayanda there who became so insensitive and scoulded me of my voice being high.I told him i wanna speak to the dr that made my test narrating him what is happening.The dr called me back confirming that indeed i am positive with COVID 19.I fumed because of the following. 1.I tested on 26/06/2020 me and my son and on 02/07/2020 got sms result from Medicross that both of us are negative,i called them for verification and they confirmed us to be negative.That day I moved to share a bed with my child and also went back to work. 2.While i was at work on 06/07/2020 boom another sms from Medicross came citing that i am positive and my worry is that i might have infected my child,i might have spread the virus to my fellow colleagues and other citizens. 3.I was given false results that i am confused which ones to believe and if the results are mine and childs trully and that alone traumatizes me. 4.I broke my quarantine which the dr said from26/06/2020 to 02/07/2020 its 10 days so i need another 10 days at home.I mean thaat easy what about the child that i might have infected and my fellow colleagues?One has to take responsibility of the damage caused by this.I demand: 1.That they retest myself and my family as damage control. 2.They need to write to my employer narrating the story that it is their fault that I went back to work sick with COVID 19 as I dont wanna be prosecuted to have spread te virus. 3.They need to organise my family counselling sessions and pay for it because we are traumatised
