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. They will absolutely be able to keep you up to date with your situation regarding the call charges and your billing.
Keep us posted on how this goes and let us know if you need anything else.
