E-Stores Direct Lay Z Spa Paris Inflatable Lid Top - Replacement Part

I ordered this product as I needed a replacement for my lazy spa Paris model as my original one popped after three summersI inflated it placed it inside my tub I did note it was much thinner than the original one and very slightly smaller The next day it had deflated and filled with water which was rather disappointing after one day at the price of £69.99 its impossible to print off the return labels and after a week still awaiting company to email me advice
