  • davidelhalil David Hall (@davidelhalil) reported

    Thinking about leaving @O2 and have been on hold for over 30 minutes waiting to speak to somebody about it. Is this part of your customer retention strategy?

  • MsCee_Em Chile (@MsCee_Em) reported

    Ever since my phone got automatically updated to 5G it’s had the worst signal ever! @O2 this may be the start to the end of a loyal 15 year relationship. 5G feels much slower than 3G.

    @O2 if I stop using my O2 contract for 24 months will the contract cancel down by itself due to inactivity?

  • vickidoylexx Vicki Doyle (@vickidoylexx) reported

    @O2 not a happy customer. Upgraded my phone to a Samsung Galaxy S21 with 1 week delivery. As soon as i placed the order i had an email to say out of stock. Now you can't tell me when it will be delivered. Not impressed at all.

    @O2 I've already been talking to you via DM and you rarely read the full message/conversation! The service has been shockingly bad and losing months of my Disney+ subscription because you don't read/understand! I started migrating my service last night! #Goodbye #GoodRiddance #NotoO2

    @O2 @o2 bet your forms work better than your customer service and sales team. Two weeks of different instructions and still hant been able to purchase a pair of airpods. This is what puts me of o2😡
