What a sham of a company firstly wronngly bills me 1054 for a return they had in their possession due to pac code transfer error second tried to upgrade two weeks ago paid early upgrade fee of 500 pound as I broke my tablet and my work relys on one. Ordered an iPad pro next day delivery stated was in stock next day gets an email stating awaiting stock from supplier went on to chat for them to cancel my order was told to wait 24 hours for the system to update 12 days later still telling me to re pay the upgrade fee and O2 still haven't refunded me the original upfront cost tried to sort this myself and had the call temrinwted by O2 multiple times. Just stay away if you don't want an head ache looks like I'll now receive my device after Christmas not happy
