Section 8 - rent reduction?

[Lynne M.]

I got a section 8 notice through stating that my Hap payment is $704

but tenant rent is $0.

Why have they reduced the tenant portion to $0 when it was previously $96 ?The rent is $800 and the tenant has been paying $96 for almost a year now.

The rent is still $800 - so I would either be $96 short each month or I would have to terminate the lease?

Is this normal?
