Palmstreet Vitta arrived soaked w major rot...

So I did 2 day shipping w extra insulation, yet when this plant arrived it was soaked and out of the soil. The heavy soil was so wet it soaked through the paper and batting. This cause the roots to rot and I lost about 90 percent of the root system.

The seller offered 25 percent refund or to ship it back for a full refund. I'm wondering what I should do. I wish an option could be to give it a few weeks to see if it starts putting out roots and remains healthy.

The seller is aware I need to ship the plant back from NY to Florida w no heat pack. I'm afraid sending it back will just kill it with the stress it has already had. I'm just not confident about keeping it and that it will do ok. What do you think?

The 2nd to last photo is after trimming rot and the last photo is the plant potted up.

Thanks in advance for any insight!
