Hi,
I got refused in December as well and immediately reapplied attempting to answer their concerns. That's the much you can do.
Reasons for my refusal included personal assets and finances and I included 2 property owned to I and my hubby. They stated status of current country of residence and I attached my PR for south Africa where I reside, they also stated may not return and I outlined a business plan of I and hubby to open and run our own business based on the course I was going for.
So fingers crossed. Maybe second time a charm
Good luck to you.
