Honestly, I don't even know why I bothered. So I received a text from Halfords to say my camera fitting was booked Sunday, and my camera had arrive for Click and Collect:
Me: Hi, i'm here for my dash cam fitting appointment
Hal: Erm.... a dashcam fitting?
Yes, I'm booked in for today.
Hal: Erm... how?
Me: sorry, what? I purchased a dash cam and selected today as a fitting date?
Hal: Oh, ok. How did you do that?
Me: Sorry come again?! Via your website?!
Hal: Oh. Erm, we can't fit it.
Me: Why?!
Hal: We don't have any fitters.
Me: So why did the site let me book it then?!
Hal: Oh it does that. Been like it for ages.
Me: It lets me book when you don't have fitters?
Hal: Yes.
Me: Refund me the fitting, I'll do it myself. Can I have my camera then.
Hal: You ordered a camera?
Me: Of for f@cks sake, YES I ORDERED IT ON YOUR SITE!
Hal: To come to store?
Me: YES!! I have a click and collect confirmation. It's at your store right now.
Hal: Erm, hold on...
So it took two staff and another long wait to even find the camera.
So, on to Amazon for a fitting kit
HERE (hopefully this will be OK for the MG5). Just need to find out which fuse to use!!
