Unimpressed Online Customer Service

I recently upgraded my contract. On 31 August 2026, I received my new phones. The charging cable did not last a week. I went to the Canal Walk store and they stated it was an online deal hence I need to contact online. I contacted the After Sales online Call Centre to be told that I should call Customer Services who referred me back to the After Sales online Call Centre. Having explained that my charging cable was faulty. I was told to return the phones and the cables. The return of my phone would mean that all my data had to be deleted and reinstalled when I receive the new phones! The solution was simple - just replace the charging cable via courier or give me a voucher to collect the cable from one of the retail stores
