Pick and Pay are selling inferior products from 3rd parties!

My wife and I purchases 2 "corning ware" clone bow;s with lids two months ago. We are in our 70's and have used "corning ware"-like products for decades and understand their limitiations regasrding abrupt temperature changes. The first of these Pick and Pay sourced bowls split in the first month. The second split tonight. Both were never subjected to any stress. I took the first one back to Pick and Pay after it fractured. They said it was supp**** by one of their suppliers and therefore would not replace it. But they provided a contact to the supplier. I tried to contact them. Thry did not answer even though I left contact information. I am unhappy that Pick and Pay are supplying inferior quality products without taking any responsibility for them not being what they claim to be!
