Terrible customer service

If I could give a rating of Zero I would. I am trying to login to my vodacom on line and they are sending the OTP to a number they themselves disconnected. Now I call the customer care line and they are unable to assist they keep transferring me to a different number and the blocked my number stating that there is a high number of calls from my number, they blocked it to prevent *****ulent activities. I will cancel all my vodacom contracts as soon as they expire. Is this how you treat your clients?????????
