We purchased 2 square 10x10 offset umbrellas in March 2019 because of lifetime warranty. We paid $700. Well, less than 3yrs later(1/2022), one has completely torn off and the other ready too. Plus the fabric is disintegrating. I called the warranty number *******656 on 1/31 and 2/4 and also emailed to *******@patiosunbrellas.com on 1/26,2/4 and 2/15. STILL NO REPLY
