I decided to purchase a mobile phone from John Lewis paying £100 more than other stores as someone said their customer service is good when something goes wrong. My partner also purchased the exact same phone from Argos. Both phones showed common faults so we have reported it to John Lewis and Argos. Argos didn't even question the fault, sent a return label for a refund. John Lewis questioned the faults but agreed to repair the phone. They said if I take it to the store it would take 28 working days, if I post it to them, it would take more than 28 working days! This is such a long time! I wish I had bought mine from Argos and it was £100 cheaper!
