Reselling my old hosting account

Hello Cloudways community,
My name is Tom, I am new to the platform and could not be happier.

One thing I did not anticipate with this change was having an issue with my old host giving me a prorated refund for my service.

Siteground is my old host and I was wondering if anyone had any tips on how I can resell (its in their terms that I am able to do this) to someone. I have GoGeek, grandfathered into unlimited install that expires in Jan, 2023.

I was hoping that there might be a place on the internet for this kind of thing or any tips or suggestions would be very much appreciated.
