Bottom line. Your email was in regards to wanting posters made , not just an issue with your order. I have not had time to go back and look at the images as of yet to see if they are even high enough resolution to support enlargement. As I recall they were fairly low resolution, and so I'm not going to respond until I have the issue fully addressed.
So, no I have not returned your call as of yet. Thats my fault, because I have failed to allocate the needed amount of time to addrsss the issue. My apologies.
