I’m a newbie to Bark but i’m absolutely delighted that this came up on my google search. I am an accountant by trade and use excel heavily but it seems to take forever to calculate simple formulas. The machine was generally slow also despite it being less then 2 years old. The engineer from Goldstar IT managed to speed the machine up remotely and now it runs like a dream. I will definitely be using and recommended this service to all my friends and family. A true 5 star service.
