Telkom Staff Incopetent

On the 29th of December 2017 I app**** for Internet line upgrade from 4mbs to 10mbs and I was attended by Nontobeko Pretty. She took all the details and said , it would take 72 hours to upgrade. On Tuesday the 2nd January I tried to query as to when the upgrade would be activated and the above mentioned lady said that there is no request for upgrade. So I had to do everything from the start. Today I tried to login into my email account, which I have been using since the early 2000, I could not get in. I contacted Telkom and was told that the email has not been activated, but I explained to her that it is not a new email address and I have been using it for long time and never had problem in logingin. Anyway she activated it and i accessed it and to my horror all my email correspondence has disappeared. So there I go back to calling Telkom and was told that due to my upgrade everything gets reset and I loose all the data in my email. This new person tells me that I should have been warned by Nontobeko Pretty to download and save all my emails, which SHE DID NOT INFORM ME. I have got some important documents in my email and I am at a loss because there is nobody in Telkom who can give me a positive feedback. All I hear is "OH, I AM SO SORRY ", which does not help me at all. TELKOM SERVICE IS INDEED PATHETIC. Now the question is, how do I get my emails back?
