I bought a laptop from John Lewis just under a month ago but I am really disappointed with it. There isn't anything massively wrong but it just isn't particularly quick and generally hasn't impressed me for the money I paid.
When I bought it the man that served me said I could return it within 90 days. Annoyingly I have saved all of my files onto it and have been using it (and tried to love it!). Does this matter? Will I still be able to return without any problems?
