Impossible to contact you via e-mail

I have been trying to contact Vodacom for more than 2 months via e-mail but I do not receive any feedback. I can't contact you on the \Contact Us"section of your web site as I don't have a South African telephone number. You have no published e-mail addresses available for contacting. I have been using addresses like [Email Removed] [Email Removed] [Email Removed] and so on but apparently a communications company doesn't have any contactable e-mails."""
