POOR SUPPORT

I am assisting my mother (age 68). She does not know what to do anymore. She submitted a request to change her phone number on 18/11. The previous phonenumber is out of use for almost a year, so the sim was cancelled by Vodacom. She received a mail that it would be done in 48 hours. On 21/12 it was still not done. So she resubmitted. This time she received the mail and then a request to submit a selfie with het ID etc (Which one can understand. It is for security purposes). This she did. Then they let her know that they now want to phone her as well. She let them know the time - nothing. This is not good enough for a cryptocurrency world where price can move quicly.
