In which case I sincerely apolgise for taking up your valuable time in having to read it and reply to it.
Oh wait ... you didn't have to read it or reply to it, you could have just ignored it.
Silly me, I thought this was a forum to discuss this sort of thing. Pardon me, I'll know better next time.
Yes silly you for making a pointless post, I feel you only made the post to purposely make a point to those that recommend the brand.
I look forward to the posts from where you've tried to contact any of the others on the list that hasn't met your satisfaction.
Will you make more posts like this for other brands...? Likely not I would imagine.
For what you've posted you should be looking at vaillant, Baxi and Worcester they have big service teams and are really well covered country wide.
Intergas are good but are small in the UK and don't have the same resources as the others.
