Poor service Herotel Klerksdorp

Good day I am a Unisa student and have been asking for the last two weeks for a letter of confirmation from Herotel Klerksdorp, which Unisa requires, as proof that following the devastating storm we had in Klerksdorp on 25.11.2021 which caused us to have no internet, resulted in me being unable to write my examination on 26.11.2021 and that the service was only restored later in the afternoon of 26.11.2021. If I have made one phone call I have made 100, but of 16.12.2021 at 16H00 I have still had no joy out of them. The account number in question is VAN441
