Help with a credit issued to my account by o2

[VABooth]

Following a very long conversation with o2 via phone in store and via phone at home, a credit of £163 has been issued to my account to enable me to clear the handset balance and therefore upgrade. This has been issued to my next bill therefore I am still unable to upgrade despite this being discussed at length earlier today. I would like to complete my upgrade ASAP as discussed this morning. How can this be resolved please

Looks like you should contact the sales team as they can help with that – message them on Social Media if that works best for you -on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255
Thanks
