I received text about next payment but I'm no longer a customer

[Pensils]

I have been a pay as you go customer of O2 for decades with a rolling bolt on service for a long time. I recently had to cut back my outgoings and so changed to a sim from another supplier. I took my number with me and everything was sorted and complete by 25th of last month. However, despite logging into MyO2 where it says I have no products, I still received a text today saying that my rolling plan amount is due to be taken from my bank in a few days. I can't cancel the plan as my O2 account says I don't have any current products. I also never got a refund for all the 3 weeks that my last rolling plan payment covered that I didn't use because I had left.
I can't see how to contact O2 and ask them anything about this - it's all rubbish bots and apps I don't want to install.
Can anyone help me and tell me how to claim back my unused credit and stop O2 taking money out my bank for a plan I no longer have?
Thanks

Thanks, slightly put off by the long wait times, but might give it a shot
