In fairness, OP said he'd automated it.
I don't have that problem, because I have no credit, and can only use my phone on WiFi anyhow...
PAYG sucks so much these days. I used to be able to top up £15 twice a year. Now that £15 is gone in random data charges after a few weeks. I don't make any freaking calls.
Sounds just like my sister, 41 years old and can't phone anyone or use the internet because she never has any credit.
You can get contracts with 4 or 5 GB of data a month for less than a fiver a month, not a lot more than your old £30 a year top ups.
