Misleading upgrade information

I received a sms on 13 August advising me that I can upgrade my contract via the site and when I did that the site advised I am not eligible for an upgrade.<br> On 18 August I received an email advising me that I am due for an upgrade. I phoned the number supp**** and I was advised that it is a mistake and I can only upgrade in October.<br> <br> I went to two stores and they also advised I can upgrade via the site.<br> <br> What nonsense. Vodacom obviously do not know what they are doing or their staff is ***********.<br> <br> I can surely not be told to upgrade via two different mediums and on two different dates and it is seen as a mistake.<br> <br> Is this Vodacon rather than Vodacom???
