SARS data harvesting and buggy e-filling

SARS is stuffing me around! Documents was uploaded and submitted the 31 July 2019 and was told now by Tumo at SARS I didn't submit my files. I can login and see all my documents SARS requested being on e-filing. Then Tumo told me he doesn't know where my files are because SARS doesn't have access to my documents ? Where am I uploading my documents to on e-filling if SARS doesn't have access to my private information ? Who is harvesting all our personal information or who is SARS selling our personal information to without my consent ? While on the phone with Tumo he asked me what browser i'm using? I said firefox. Then Tumo said i should use Chrome. I asked him what browsers is supported and he said IE and Firefox is also supported but Chrome works better. Then I said i'm not using any Chrome due to Google also harvesting personal information and told Tumo i'm going to use IE. Firefox didn't want to submit and Tumo said I must hand in my documents in the branch ? I told him my documents was uploaded and submit wasn't working when I tried submitting again? Is this a known issue with SARS? When I logged in to IE the submit worked. How can SARS say when files are uploaded to e-filing the documents is not with SARS ? Who is the 3rd party accessing all the SARS documents ? Please educate your staff about telling clients what browsers are supported with e-filling ! Now SARS want me to wait another 21 business days due to the buggy e-filing platform ! ***
