how to get more info on a letter from UK Visa Immigration

[kanaga]

I had applied for UK settlement (dependent) visa. I got a mail from UK Visa and Immigration mentioning the following:

Your application falls to be refused solely because you do not meet the income threshold requirement under Appendix FM and the related evidential requirements under Appendix FM-SE

We meet the above salary requirement. They are mentioing that we can do the following:

In the meantime, if you submit any further information or document(s) relating to your circumstances, and/or those of your sponsor, as they were at the date of your application, or in the relevant period(s) prior to that date, this will be considered.

Anybody faced this kind of problem?

Did you supply all the required specified evidence?

Does the letter/email not say.... If your application....?
