I went into the Grantham store for help with my portable WiFi hub, as I was out of contract and wanted help with the process. Chris in store was an amazing help and he also helped me with making sure that I got the right device for myself as well as helping me with my phone contract at the same time. He was a brilliant help, great and easy to talk to and an asset to your company, and I would highly recommend his support to anyone and the Grantham store overall. Will definitely visit store if i need support with anything else.
