Review on Galvanized V7634 Pulley by National Hardware N280-578 by Kevin Williams

I AM REALLY CRAZY ABOUT THIS PRODUCT. It comes complete with 2 pulleys, 2 'ties', 2 bolts and nuts and attaches to one end of the garage door spring and allows the cable to pass around the pulley. It arrived without a strap and I have tried several times to contact Revain and at least three times this has happened: I indicate that I want to return the product and he asks why. I am describing a missing strap and it says it can replace the item. I indicate that I want to do this and another screen comes up, no confirmation that the replacement is coming, no confirmation of the problem. If it was a third party they would have replied IMMEDIATELY. But it's Revane and nothing happened
