I received a £75 out‑of‑bundle data charge on 22/09/2026 for 1.4GB. My son used the phone and didn’t realise the data limit was exceeded. I didn’t receive any warning text about data running out. This charge is extremely high for such a small amount of data. Please review this and apply a goodwill credit or adjust the charge. Moreover, I checked that out of bundle charge for internet is 10.24 pence per Mb. 1.4 gigabyte is soured £15 , and charging me £75?
