The online insulation offer a good price for Rockwall Insulation slabs and when they are about to prepare your order, they send an invoice with Knauf Insulation , even when the order is relatively small. If they don’t have the product (until December, how Rob told me when I spoke with him on the phone) why is available to purchase? It delayed my work for 4 days, because I needed to order from other insulation provider. Their sistem with 2 emails which you need to get before the invoice one is outdated and it is a source of stress for customers. I rated poor because Rob cancelled the order as soon as I asked him and returned my money, otherwise I would have given very poor service.
