Report
Disgusting customer service sending bullying emails to an elderly gentleman who needed assistance from you regarding your product which you installed on his home which is now failing and is still in guarantee period under your product guarantee of 25 years. When he emailed asking how you could blame the installers (as this was you who did the remedial works on the initial faulty product) instead of a reply he got a miss sent email which was clearly meant for internal not a customer speaking about him in a disgusting manner! Absolutely disgraceful! Instead of sending snide emails about customers
