Carphone warehouse sold me a phone contract with an iPhone XR in March 2019 on O2. As reported by O2 and Apple there was software issues with the phone and O2 so for 6 Months+ I was not able to use the data properly as it kept cutting out. Carphone warehouse kept passing me around and finally took the phone in for repair after more than 6 months. Shops and Customer service field to provide suitable compensation for the lost use of my phone and delaying the fix. I was still paying £50+ a month for the phone which I could not use fully and felt I should be due a small refund to compensate the additional I had to pay when I could not use the phone. Now they do not reply to my emails. They are useless and will never use again. Rubbish customer service as they send template answers and each email is from someone different so you have to keep explaining the problem.
