Applied yourself or through consultancy? I will be applying for visa soon, possibly this month itself.
If financial reasons are the reason for your rejection, you have no choice but to show more money. Make sure you show bank statements, fixed deposits or educational loans from a reputed bank. You can also show a stable source of income like salary slip, employments/income letter or business if parents are employed.
Provide as many supporting documents ( investments, property evaluations, income statements etc.). However, make sure these documents are relevant to your case. Also, do not forget to upload
all the required documents. (academic transcripts, english proficiency test scores etc)
If you are not aware of the application system, hire a GOOD consultant to help you out.
Additionally, you can make your explanation letter (SOP) more convincing and genuine. ( DO NOT USE TEMPLATES FROM THE WEB). Explain educational gaps if any. Show the link between your high school subjects and the subject which you are planning to apply for in the university. Provide proof that you will return to your home country ( parents in home country, property evaluations, responsibilities in home country, job prospects etc.). If you cannot provide proof then just explain it in the SOP. If your academic background is not good then explain the cause. Justify every possible question the visa officer may have.

DO NOT REAPPLY IF THERE IS NO CHANGE IN YOUR SITUATION. YOU WILL BE REJECTED FOR THE SAME REASONS. GET CAIPS NOTES IF REQUIRED. DO NOT USE ANY FRAUD DOCUMENTS.
I haven't applied yet but I have become paranoid by the though of rejection, hence all the research
.
I hope this helps. Best of luck.
