Shabby Service and Communication

It started with me calling them re a printer I wanted to purchase. When arrived at the address noted in their wed site. Discovered that they had moved location. This point was not communicated to me while on the phone to them?? Then had a issue that needed attention so was told they can attend to it immediately while I wait, must just bring it in. So did only to be told that no now would need to book the machine in for the modification discussed the day before. Then was told that could get loyalty points for my purchases. Ok but this was not divulged when made initial capital purchase of the machine. No problem was told just send invoice ref numbers and points can be allocated. Did this over a week ago not even a acknowledgement of my mail or subsequent follow ups.. The guys are pleasant enough but there's certainly room for improvement.
