I would have them send me the Bella solids (if I still wanted them) and cancel the rest of the order. I'd also check and see if I couldn't get free shipping or a reduced rate on the fabric or even a free yard or two of fabric for my trouble. The fact that YOU had to call them instead of them being proactive and calling you about this is not good business practice. Actually I would insist on some form of compensation or I'd cancel the whole order whether they've cut it or not.
