    @O2 I’ve been contacting O2 since the 20/06/25 because my phone won’t connect to mobile data or Wi-Fi. After numerous calls with customer service I’m still no closer to getting it resolved. Customer service tells me they’ll call at specific times & don’t bother calling &

    @KyleTSpence @MartinSLewis @O2 Their prices are horrible though, and their Giffgaff MVNO has worse speeds than proper O2 unlike ID Mobile/Voxi which are just as fast as Three/Vodafone.
