VODACOM NEW APP

Vodacom cancelled their user-friendly App “My VODACOM” without any prior notice. When I opened this app today it was directing to ‘VODAPAY” APP which has many conditions attached in the Terms, including monthly Payment. It put me in a situation where I can't even have access to manage my current airtime or data or buy any of them. Is that a legal move from Vodacom? Very frustrated customer. Dr Rita Waisberg
