Hey SteveBrett, thank you for reaching out and I am sorry to hear you are having some issues upgrading.
Since the 1st Jan 2023 My Rates has been discontinued and replaced with the O2 staff sim deal.
If you are currently on a My Rates deal you will not lose the discount however if you made any changes you would lose this, so for example in your case if you wanted to upgrade you would be paying the price on the letter and discount would be lost. Thanks
