Anyone know if Clearline lightning protection has closed down?

I sent 2 units for assessment ... possibly damaged due to a power surge around July 2019

The units were cleared as OK ... however when i replaced them on site 28/08/2019... we started experiencing a few issues with the display and the units would not energise within a few days of replacing the units.

I sent the units back to clearline ... dealing with their technical deapartment (Paresh) ... I was then told the batteires in the units had to be replaced and that was the last i heard.

I contacted them to follow up a few months later still nothing.

Its now 25/06/2020 ... i have tried on numerous occassions to sent emails ... with no response.

Today i tried all the numbers ... not one number was answered ... i can only asume they have closed down.
