I had horrible experience with teamknow and Currys - how I bought brand new Samsung ultra 250 which was faulty and after few months started to give issues! Called Currys and team knowhow booked it for repair and said they will repair and return it within a week - but more than a week passed by no news no mobile - chat help line is not helpful as they saying they don’t deal with online issues or repair. Phone helpline is not working as no one knows what happened and kept on putting me through to other departments. Last text was delivery is on Monday and then after 50 calls a voice message that it will be delivered tomorrow but seems that tomorrow wouldn’t come! Used Currys twice both times horrible experience do not buy from them especially expensive items in my case it was about £1300! Biggest issue is with mobile you don’t know as it still might have my personal data so I’ll have a very uncomfortable Christmas and new year - thanks to horrible Currys and useless team knowhow
