Pls I need advice Urgently.

I work in medium size multinational firm in Nigeria with a monthly salary of 129K after deduction.A was recently refused UK entry clearance for a company sponsored seven days training with a company who we represent in Nigeria thus I applied for administrative review, surprisingly d refusal was upheld.

Reason
Credit n cash in my saving bank account not commensurate with my stated monthly income of 129K thus on a balance of probability ---------------------------------------------------

I submitted payslip and payment cheque in the stated amount for six months.my company bank statement also contain detail of cash withdraw of 129K monthly by me.I withdraw cash on d counter n pay into my saving account.
The entry clearance officer ignored all the evidences i provided n upheld the refusal.

He stated dat my explanation has been noted but the refusal decision is being maintained. advising me to apply at anytime and i should attempt to address the concerns raised in the refusal notice.

I had about 400K in my account when i first applied. presently the sum total of my saving has gone down - lower than 400k.

Please can re-apply right away as my company advised or wait for sometime?
