Probably best to resolve this issue by using the iD online Live Chat service, to speak to a customer adviser ​@jc0910   

The advisers work until 8pm on weekdays and 6pm on weekends - just tell the 24/7 chatbot you’d like to “talk to a person”.

Hey there ​@jc0910, we’re sorry to hear that. We hope that ​@MZone was able to help and you managed to contact our live-chat.

If you still require assistance, please do let us know.

Thanks,

Tyler

I couldn't make any calls for two days. The message shows 'phone network is not available'. Can anyone solve this problem for me. 

Hi ​@Sabrinaluo sorry to hear this.

What phone are you using, have you tried a reboot? What is your post code please?

Hi ​@Andy Clarkson, ​@Sabrinaluo and ​@jc0910
