    Could someone at @O2 explain why the service in BT61 has been diabolical for almost two weeks? Bit of a nerve advising us of a spike in bills alongside a drop in service? Not exactly sure what I’m paying for at the minute.

    @O2 @kaphillips6184 I’m not signed in on any other devices and haven’t accidentally ‘used’ the code. It’s been saying voucher used all week. My partner has the same issue, and definitely hasn’t got priority on another device. We wondered if it could only been used after a week has passed, rather

    @O2 @o2businessuk are your “promotional team” currently running a campaign during which they actively call customers, but have zero insights into their accounts and ask to disclose information such as my last bill? Very suspicious, bad form and reason to move my custom elsewhere.
