We have to use D & G because our parts are covered for free for a few years yet. But we pay for the engineer. Bizarrely it was cheaper to take out 6 months insurance, that covers for multiple break downs in that time, then to pay for a one off visit. In our case that’s worked well because the first repair didn’t solve the issue. The first time he ‘happened’ to have the part on the van. The second time he didn’t have the parts, so had to order them and arrange another appointment. But D & G cancelled the second repair appointment 3 times, at short notice, with no explanation. Just a text! There was no way to talk to anyone about rebooking. Just on line and sometimes the text didn’t include the booking ref so I couldn’t go on line to do anything. It was Extremely stressful and very time wasting. The engineer didn’t know anything about it, as the appointments aren’t booked by him. Why do they not have parts on the van when you’ve told them what machine isn't working? However the engineer is Brilliant and I’d give him 10🌟. He’s thorough, professional, friendly, explains what he’s doing and why, gets I touch when he’ll be delayed.
