    @O2 new customer here! My one time passcodes don't seem to work which means I can't get access to O2 priority. Same issue happened with the My O2 app but that one let me change my password via email so I can now access. Is anyone able to help?

  • Force94557433 Force (@Force94557433) reported

    @o2 im really disappointed in the customer service levels at o2. My new phone contract has not been working and promises of call back from customer service also not happening. Thinking of returning the device and cancelling the contract.
