I’ve just received my new handset but it’s faulty when making calls can’t hear or be heard. Tried calling 02 13 times and they’ve hung up

@tiggz You can try to reach O2 via social media:
Facebook (https://o2uk.co/O2CFB), Twitter (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255
