Vodacom will not finance my phone on upgrade

I was at Vodacom in Wellington and wanted to upgrade when Christel informed me that I can't because there is a block on the account. My father is a loyal customer of nearly 15 years, he has 5 contracts under his name. Because my father is self-employed he always arranges with Vodacom. His account is paid in full. But the problem is: Vodacom won't finance the phone that I want to upgrade to. This is a disgrace because this isn't the first time that this has happened. Two years ago we had the same problem. I am very unhappy with Vodacom's service and I need feedback as soon as possible. If my upgrade is unsuccesful, be sure that we will end all of our contracts.<br> <br> Regards,<br> Mikyla
