Poor customer service

1) I have an account with 4 phones and I'm unable to upgrade any one of them online because I have a prepaid phone. This is because your system \looks"for a postpaid number to send the OTP to. Instead I must queue up in a shop or phone someone to do this for me. Why is my phone not a problem in every other online company in the world?? 2) I've had an account at Vodacom for about 13 years but I cannot see my online bill or any phone or packages on this account. I have to phone your help desk and they must send it to me. Why is that?? I don't have any problem in ANY other company I deal with for all my other accounts so why is Vodacom unable to provide such a basic service to its customers? 3) When I was emailed the account invoices there is nothing for one of my numbers and another one we did a sim swap for shows the incorrect number. So now my billing invoices are incorrect.<br> """
