“I spoke to you on the phone today about my oven that didn’t work and you explained that when I fixed the button on the timer/clock etc you thought it would work OK.
Strangely after I spoke to you I walked to the porch to collect the post and there was the envelope with the part we had ordered.
I just wanted to thank you for your advice and to say that it does now work OK.
I really appreciate your help and the fact that you did not just come out and charge us the call out fee. We will certainly contact you in the future when we have a problem.
