Disable auto purchase

Keep in mind, you can block international calling by several means on your account as well as through roles. 

I have had a UK 0800 Ringcentral number for 11 years and was just today charged 10+VAT for a 'Auto-Purchase Calling Credit Package' which I did not agree to or sign up for. An agent from Ringcentral explained that it was because I had tried to make a call that was out of my calling package. I explained that this must be a recent change (in order to generate more revenue for Ringcentral I would imagine) because before today, if I tried to make a call that was not in my calling package it simply would not connect. As I type, the agent, at my request, says "the auto-purchase feature is being disabled" something that I can not change in my account online (how convenient). The agent also said that my 10+VAT is being refunded and that I "can keep the existing credit on my account" as a gesture of good will I would imagine. I now just have to hope that the refund and the auto-purchase cancellation will actually happen. I find it quite unacceptable how companies seem to be finding ways to add an auto-purchase / auto-renew features to accounts without customers direct permission, even if they change their terms and conditions and in the process do not feel obliged to explain this major 'update' which they brand as a "convenience" rather than call it what it is - gross negligence / theft as far as I'm concerned!
