Open O2 Not allowing me to apply my Military Discount code

[Ewen1]

I was told in-store that my military discount would be added after my second month of payments; however, I have now found out that it has not been applied for my entire contract. I am now trying to set up O2 open however, it comes up with the error code 'sorry, there has been a problem'. Is there a way to reclaim my lost payments from the months of the contract, without a discount code, and receive the discount for the remainder of the contract?

Many Thanks.

You need to apply within the first 28 days.

As the store should have done it correctly, and didn't, plead your case to O2 on social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (X)  (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG)
