So tried to get the computer today. Emailed Evetech and Partserve got no reply.
Then I called Partserve, said all kinds of stuff, Evetech booked it in, I couldn't really understand everything so I asked to email me what I need to do to get my laptop back.
Hour later, called again because obviously hadn't received an email. Spoke to a lady this time, she says we're good to go, I can arrange a courier it's ready for collection, she gives me the address etc. Great.
16:30 I get an email from Courierguy, collection failed. Obviously I'm a bit frustrated. So I call, no laptops apparently still in the workshop. They'll call me tomorrow at 8:30 apparently to let me know when/if it can be collected.
