    @O2 Another year and another price rise, very poor considering the current economic climate/situation. Will definitely be looking to change network when my contract ends

    When you upgrade your contract with @O2 (keeping the same number) and they delete all your saved voicemail messages from your Granny who passed away 💔 #broken

  • TheRealRead Aaron Read (@TheRealRead) reported

    @O2 I’ve DM’d. I’m pretty annoyed about this so may consider cancelling the order and going to another network. Lying about stock levels to pile up orders isn’t a quality I’m looking for in a service provider.
