Big Local North Cleethorpes and VANEL have teamed up to provide a free IT support service to local people, and if you live in North Cleethorpes then I can help you. I work out of 82 Grimsby Road (the Big Local offices directly opposite Tesco Express) and all you need to do is make an appointment and pop in. I’ll answer your questions, solve your problems, give you advice and do what I can to help you get to grips with computers, the internet and more.
So, if you need any help then make an appointment and I’ll try and help you.
