Hello, I want to dispute a billing charge of £1.60 for a 3-minute call made to the number 447700179578.

According to Ofcom regulations, the 07700 179578 range is strictly reserved for fictional drama/media use and is non-operational. It appears your automated system has misidentified this dummy number as a chargeable or premium line.

Could you please investigate this billing error and credit the £1.60 back to my account? I would also like to double-check my account spend cap to prevent this from happening again. Thank you.
