ACTUAL BEHAVIOR
---------------
Balance Impact is incorrect for the subsequent usage after performing Modify Bundle Operation. The modify operation can involves the subscriber deletes/rests balances associated with an existing bundle. Possible scenarios are:
Delete usage i.e. reset allowance, delete topup, delete rollover or any combination of the afore mentioned. There is a wrapper opcode to read the valid balances and perform adjustments according to the input parameters.

From the above, used units are 405798912 bytes (387MB). However, the consumed reservation is not matching with 387MB.


EXPECTED BEHAVIOR
-----------------------
The consumed reservation should match with 387MB.

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Check account balance before modifying bundle
2. Modify bundle operation
3. Pass CCR Update Request (CCR-U[3])
