Qualification Verification could not be done

Worst experience ever. I studied at Damelin Braamfontein in 1995 to 1996 Marketing Business Management 1 year Diploma . A company i app**** or a job did a qualification verification in January 2024 to no avail have they responded. I did not get the position because qualification check was not successful. I have reached out this year as well to no avail. I am very concerned on the integrity of the institution. I would like a refund please on my tuition paid.
