When you say not over SEing at the same addy would I be calm as I’ve only done it once

If I'm understanding this correctly, If you've only used the same address once, there's no cause for concern.

Just don't abuse It by hitting one SE after the other, particularly In very close timing.

also does it have to be spaced out

As per above.

or I can just do the refund again in the same week to the same addy

To play It safe, It's best to allow a sufficient gap.

Last time I done it was 9-10 days ago is it safe to do again to the same house or should I wait
