    I came into the Grantham store to query about getting an upgrade, Ryan was really friendly and helpful in the whole process. He was really informative and patient and answered all my questions! Definitely easier to come in store as opposed to online and would recommend! Thank you for all your help! 😁

    Worst service ever, spoke to like a piece of crap not like a human being made extra work for the customer due to the id having a different address, tried to help and got treat worse when trying to solve issue. Had to have extra security check due to personal issues and got told to come back because it took too long( after they made me drive back for ID which was an hour) and then had to leave without a working phone and got told to try online when I couldn’t with a broken phone. Chris should not work there and after reading other reviews other people feel the same way !!
