I appreciate you contacting us on the forums about the billing and call charge query you have and a warm welcome to the community forums.
I have taken a look at this for you and can see that you need to get in touch with our teams about this.
I understand that if something has changed on your billing you want to look into this and to do so it would be great if you could get in touch with our teams via the secure methods below.
You can contact them to look at supporting you with this this either via 150 or 0345 454 1111 or via Webchat
To speak to the Webchat teams just choose the option in the column on the left that best matches your needs and tab over to the right through the menu to get to the Chat Online option.
E.g.- Account and Billing > Manage Your Account Online
Via these options our teams can clear security with you and support you with billing or packages queries. As the forums are public, supporting you in this way is the best way to keep your data confidential.
