Salary update for dependant pass privileges

hello,

I have been in Singapore with my Husband since March 2020 on STVP.
My husband is on Spass , and we waited for the covid situation to get better in order to have a salary increase and meet the 6000 requirement for DP. The problem is that the first salary registrated by the company at MOM was the min Spass basic salary ( 2800). And the rest was paid as commision ( 5400 in total as stipulated on his contract , with  2 payslips/ months).

In december 2020 my husband signed for a new salary at 6030 basic fix.

The MOM required 3 payslips in order to register the new salary , but because of covid again , all salary have been reduced in january and february by 10%.

In june , we finally could provide the 3 months payslips ( march, april, may) of 6030dol.
The company maid the application to update salary in MOM portail.

We were so happy and relieved at this time... but after 5 weeks waiting for this update, MOM rejected this application saying that the increase of salary was to high ( 2800 registred in march 2020 to 6030 in june 2021). They also addes that increasing salary to 6000 doesnt mean you can automaticly bring your dependant, as having a dependant  is not a right but a privilege.

We were a little bit choqued as we know it is a privilege and we were so lucky that we could stay together this year when others didn't get the chance, but we waited so long , full of stress, to finally hear that...

The company maid an appeal 3 weeks ago trying to prove that it wasnt a big jump but a gradual one , and that comissions has been consistant so they put everything on basic. 

We are loosing hope... ICA doesn't want to extend my visa anymore so I have to go back next week.

If someone has same experience I would like to know please.

Thanks
