Excellent customer service Contacted them about fixing a dead HP printer but decided it was quicker to replace it as our business can't function without one. Andrew in service recommended a Brother machine which is perfect for our requirements and Jeremy in sales arranged delivery by 10:30 the next morning (it arrived at 9:30!). I was in a tight spot and both of them did their utmost to help. I shall definitely be purchasing from them in future and highly recommend Diamondsource Ltd. Thank you.
