NWU take days to respond and not helpful.

As an old NWU graduate I am disappointed how the service has gone down over the years. I app**** to study PGCE for 2023. unfortunately something came up and I had to cancel my studies. After sending mails to ask when is the cut off date for a refund, no one rep**** so I went ahead and cancelled. I was then told I cannot get a refund for 1st semester modules as I cancelled on the 17 March and was supposed to cancel on the 10 March (a week earlier). I was then later told that the cut off for PGCE is 4th March. Being told two different stories was very confusing and no where is it clear what the actual date is for cancelling PGCE, I was under the impression that it is the 28th April. My mails are only responded to days later and sometimes not at all resulting in delays and I sadly, I only received refund for the second semester.
