Monthly tariff cancellation

[Love12]

I have been paying my monthly tariff every month. I have ran out of data this month and I recieved a call saying my tariff has been cancelled and I am being moved on to a standard pay as you go tariff? WHY? I did not request this and I do not want this. I want to start my £10 rolling tariff again from today so I have data! 
I do not appreciate having my tariff cancelled for no reason?

The only reason I can think of is if you don't have a recurring payment set up.

If you have good reason @Love12 for not having set up a recurring payment, this might interest you :-

As they said they have been paying monthly, they clearly have no issue and the fault lies with O2.

Calling O2, as stated is the only way to resolve it.
