I recently switched to a smart meter, I've got an Aclara meter, and i’ve tried to top it up through the app (this said the payment went through) but I waited for over an hour and nothing changed. So i tried to put in both payment codes in manually and both came up with a CRC error.
I have £4 left of emergency credit so please help :(

A "CRC error" on a Pay As You Go (PAYG) meter typically indicates a problem with the data transmission between the meter and the key/card, meaning the data doesn't match what's expected. This could be due to a faulty key, a problem with the meter itself, or an issue with the top-up process.
