I am so glad your situation is getting resolved. I hope you get the fabric.
I had a problem with an online company and also received no replies to emails and phone calls - I finally took a deep breath one morning and called them and left yet another message saying that if I did not hear from them within 24 hours I was going to file a dispute with my credit card company. Ten minutes later I got a phone call and finally (6 weeks later) received my purchase. There was a second part to the purchase that did not arrive for another two weeks with no instructions. To this date - almost a year later - I still have not received instructions. I just gave up!
