The pleasant lady who answered the phone knew who I was and was pretty adament that an email had been sent to me advising me of the price and necessaries - which I hadn't seen. Upon flicking through my digital postbox I found that indeed they'd sent me an email on the arvo of same day as it'd arrived - very efficient and indeed my bad. The cost of the repair was £23.50 including return postage - which by my reckoning is a bargain.
I have thus flung cash in their direction digitally and seemingly have around a 14 day waiting period! So far a great service though - I await with baited breath for the repaired product.
