Terrible customer service and impatient

This is my third time receiving poor service from Elizabeth. I have thousands of emails sent to her with no service. First, I was disadvantaged from settling my account when I had a sponsor that was willing to pay however they just needed my statement for that to happen and when I requested it many times without help I missed the dead line. On the 27th of February, I requested a pro-forma invoice for my textbooks with no feedback. I had to travel from Vaal to get information that Mancosa outsources textbooks which if I had received feedback I would have saved my time as all I wanted to get was information rather than one to tell you that they dont offer textbooks, even though she only responded to my request that I did on the 27th of feb today by a call since I requested the Deans email address which she still refused to provide me with. I still request the Deans email address and the head of Operations aswell as the GMs
