I recently discovered my electronic garage door was sticking, having bought it from Zenith Staybrite in 2015 with a 10 year guarantee, I called the company only to discover that Zenith have gone into liquidation.
I called Hydrogard Legal Services of Sandhurst, Berkshire who have taken the claim on, they have told me they can get me my money back as I now have no guarantee.
This company got my money back from a roof coating company that went bust, if you need help, call them. Hydrogard Legal Services - Sandhurst, Berkshire
