My university is suing me

Hello,
I’m in need for some advice. I went to university in 2017 to study a postgraduate degree. I was only there for 3 weeks and decided to withdraw from my course. I was aware that I had to pay 25% of the annual fee and I asked them if they would be able to give me 2 months to pay. One of the reasons why I dropped out is because I found out that I wasn’t eligible for the postgraduate loan. Anyways, since I had a bit of saving around £1000 I only had to come up with another £950, which I was planning on taking from my wages as soon as I got paid. When I was ready to make the full payment the university stated that I didn’t actually withdraw from the university and now I had to pay 50% of the annual fee instead which I found ridiculous. I explained to them that I withdrew 3 weeks into the course and they basically said they had no record of it. I refused to pay 50% because I though that was very unfair. They said that they wouldn’t accept the 25% and I need to pay 50% instead straight away. I refused, and now three years later they are taking me to court. They now want a total of £8000 for the course fees. I really don’t know what to do now, I can’t afford to pay £8000 for a course I didn’t attend and withdrew from. Any advice would really help. The university is Solent university btw if anyone is wondering. The course was a total of £5700, I don’t even know where the extra 2300 came from
