Account Status

In December 2016 I had a number due for an upgrade. I went to Vodacom in Sandton Mall, Menlyn and Hartbee****rt, only to be turned away after being told that there was a problem on my account! With no option, l moved the number to MTN and got my phone with 72 hours. I now have another number which is due for an upgrade on Vodacom and again l went to Vodacom Hartbee****rt and AGAIN l were told the same thing! My account is on a debit order, I do not miss monthly payments whatsoever! Vodacom should get your act together and provide a service. I pay the ridiculous amounts you charge me because there does not seem to be much of any choice...or is there? STOP THIS NONSENSE and be PROFESSIONAL!
