Great service in respect of delivery, it was next day. But that's where it stops. Our till is so noisy and making a loud buzzing noise, which they agreed isn't normal, even when the switch is in the off position but after speaking to CRG they refused to send a replacement and the only help they offered was for me to take it apart and have a look, which would void my warranty or for us to take it back to them (at our expense) rather than sending us a replacement. They are in Cheltenham, we are in South Wales a 5 hour round trip. We're not impressed to say the least and wouldn't use them again. Probably going to sell the till and buy one from someone who actually cares about their customers...
