Housing allowance is way too low compared to your basic.
did you mean 14500, that will sound reasonable.

would suggest, go back and check again as they made a mistake with my calculations not once but twice

where i work minimum (start point)housing allowance for any one joining is 11000.

you will find it very hard to get some thing for 4500.

same again for transport allowance way too low, minimum lease for a small car 1700 per month
