BAD SERVICE AND RUDE BEHAVIOUR OF STAFF

I graduated in BCom Honours through Unisa on 11th of May this year. Image factor was appointed to take photos during the graduation ceremony, which I paid for on invoice number 81111. They promised to send photos by email in 45 working days following the ceremony. Up to date I still have not received my photos. When I called them trying to follow up they were so rude to me. I then followed up by email and on the 3rd time they told me that photos for Unisa East London were already distributed. They requested a copy of the invoice which I sent by email. I am so annoyed with the poor service and the treatment that I am receiving from these people.
