Query: Twice Cancelled order

After my first order for this print was cancelled by PosterRevolution I decided to attempt one more time at ordering this print. After the print still had not arrived 4 weeks after the rest of my order I contacted the seller to see if they were again going to cancel my order. I was assured that I should be expecting delivery in the next week. I withheld from ordering the print at on online seller at 35% off because I believed, as PosterRevolution assured me, that my order would still be coming. I then get an email today to inform me my order would NOT be arriving and the seller had cancelled my order. So, as of right now I have no poster and have lost out on a 35% sale of it on another site. To say that I am disappointed in this seller is a gross understatement.
