Phone credit, why is my credit almost finished after a 6 minute UK call

[Ellezz]

I topped up recently and am baffled why I have under a £ left on my phone

Hello @Ellezz. 

Welcome to the community. 

Have you called the UK from another country?

Was the number a premium rate number?

Speak soon, 

Katie

What were the first 5-digits of the number you called?
