Hey there guys, this is my first every post so please bear with me. I've got whatever happens insurance and a few months ago my charger became defective. I had a charger replaced by them previously but my laptop still had to be sent of as they wanted to check the battery, I couldn't do without my laptop for another prolonged period so I bought one myself from an online retailer (not currys) Have I breached my contract in anyway by buying this?? Could they refuse a future repair because of it?
