Worldflower Garden Domes

I ordered and paid for 12 mil woven plastic for covering of my greenhouse,and was sent 10,5 mil instead,after contacting the supplier other than gardendome,to inform them of there mistake,they informed me that gardendome had been notified they were out of 12 mil at the momment,gardendome replied to them it was alright to send to 10.5 mil instead,without my approval or notification. I contacted gardendome and gave them a chance to reply,after 10 days,no response,and I told them I was going add my rating to garden watchdog,so buyer beware.
