Help! My PIP has been reduced

Stickman

I received my PIP payment this morning - £420.60

In a letter from the DWP, it quite clearly states that I will get £108.55 a week from the 8th April..  I get my PIP monthly, so that is £434.00.  I have only received £420.60 this month, why is this?

PIP is paid 4 weekly, not monthly. The rate £108.55 is the new annual increase amount. The increase didn’t start until 8th April so this payment will be a mixture of old and new rates.

You won’t see the full increase until your next payment and it will be £434.20 every 4 weeks.

Thanks poppy123456

I thought afterwards that that might be the case.
