John Lewis Broadband acting in bad faith?

I was a customer of with the e-mail address of [Email Removed] for many years. But then it appears that their internet provider, John Lewis Broadband, cut me off, and I do now know why. They do not answer e-mails, and their only contact number is a freephone number in the UK which we cannot call from here in South Africa. So I have had to abandon my beloved and very useful e-mail address and start using Gmail. The lack of service from John Lewis was appalling and the support at Waitrose did not help either.
