  • wong_jim Jimmy Yuen Ho Wong (@wong_jim) reported

    @EE's customer service on the phone when compared to @O2 is just so much better. Lovely people. Dealing with O2 is just shear incompetence and frustrations. Never leaving EE again.

    Why is my 4G painfully slow please @O2

  • searlypants The Logical Gooner (@searlypants) reported

    @O2 Have messaged you with details You say you recognise the number - is this someone genuinely trying to sell alternate O2 PAYG plans you don’t advertise online? Or is it a “recognised” scam? Why would the caller hang up abruptly when I became suspicious?

  • SammiieJoe SAM ∞🇱🇨 (@SammiieJoe) reported

    @O2 I’ve got an issue. Can’t seem to get through to customer service 😩
