Lay-Z Spa Miami Inflatable Hot Tub Layz C/w Floater/chemicals- Has Slow Puncture

Lay-z spa Miami hot tub with accessories including pool starter kit (chemicals/testers) chemical floater. It was purchased 2 years ago. We have always used 4 camping roll mats under it to protect it (new) & these are included also. 1st picture is at time of inflation, Please note- this has a slow puncture-last 2 pictures show the pool at hour 1 & hour 2 after inflating. It goes down very slowly.

Could be an easy repair but we don't have the time or knowhow. There are some cosmetic marks to the pool to be expected with a used hot tub & storage of it. The box is included but has been stored so is not pristine. Please note-there is no return on this as I have been completely honest about the slow puncture & cosmetic condition.
