Omicron in Canterbury

I took a sample in to see if they could match the print quality. They said they could actually improve on it. However the work they did fell way short of the sample. When questioned they became irritated stating "That's how the machine prints". Nothing we can do about it". The work was useless to me, as I could not pass it on to my customers. Also, I had previously overpaid on another job. They promised to refund in writing but then didn't want to actually pay. I couldn't be bothered chasing it. I went to this company with good intentions and ended up frustrated and cheated.
