A 26% cost increase is apparently a lower tariff ....

[A_Brit_Abroad]

So, my tariff signed up in July is now increasing by 26% and the opening line of the email says 'You’ll be moving to a cheaper tariff which will cost £12.63* per month'.

The old tariff signed up to was £10 a month.

I have been given unwanted, unuseable additional data allowance - and I am told that I have no choice. 

Presumably I can leave O2 with no penalties given that O2 has reneged on the contract within three months.

Is this how UK mobile oeprators opreate - charge you more for something you already don't use and then lie to you saying its a lower tariff ?

We can't access accounts, so you need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
Or 202 from your O2 mobile.
Advice from an O2 Guru to get through:
When you call 202, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
