Hey @Pradeep_Kumar1, this is a really frustrating situation.
Here’s what’s happening: when a user is removed, their seat stays occupied until the end of the billing period if they used any credits. When you add the same user back, the system treats it like adding a new seat with a prorated charge, so until the end of the period you effectively get billed for 6 seats instead of 5.
At the end of the billing period, the removed seat should drop off and you’ll be back to 5 seats. The prorated credit for the removed user should also apply to your next invoice. But I get that this doesn’t help if you’re being overcharged right now.
