Axis Bank
ATM money not withdraw

I withdraw money from Kotak bank and used Axis bank ATM.

I withdraw money 10000 from kotak bank ATM but only 2500 i got from that ATM machine.

I complained this to Axis bank and they told me after one week we will be give you status of this complain but after one week over again they are saying it will take one more week.

What should i do now?
