If you are after technical help with your phone, tablet of laptop then I will highly recommend Geek Squad. They are based in Carphone Warehouse (who they are in partnership with) and offer free and impartial advice and support to everyone regardless of whether you have bought anything from them or not.
Geek Squad was set up in 1994 to offer various computer-related services and accessories for residential and commercial clients. Today it provides services in-store, over the internet including 24-hour phone and emergency on-site support.
I first came across them a few years back at London Fashion Week when they were a sponsor and manning the press room dealing with queries from stressed journalists and bloggers.
I have used their services on several occasions and found them to be more than helpful. Their staff take the time out to help you and more importantly explain things to you in simple terms. My mum had issues transferring images from one tablet to another; they not only showed her how to do it and also explained to her how to save her settings so she wouldn’t have issues in the future.
They also offer other services such as mobile, tablet and computer repairs as well as trade ins. Geek Squad are well worth a visit if you are ever having tech issues.
You can find out more about Geek Squad from their website.
