Vodacom Upgrade Date Incorrect

I upgraded my Vodacom contract at Makro in Port Elizabeth on 3 July 2016. I received my new phone and my new subscription started on 1 August 2016. I noticed that the package was not upgraded to the new one (I was told that it will change from Smart L to Smart M or something like that) and went to Vodashop in The Bridge Greenacres. They told me that it sometimes takes a month or two. On 11 July 2018 I went back to Makro as another cellphone outlet told me that my upgrade date is August 2019 and not in 2018. Luntu Batyi at Makro was very helpful and after investigating explained that there was a system problem at Vodacom and the contracts were only captured (or updated) about a year later. I post this review to give Vodacom the opportunity to investigate and confirm where the problem lies, with them or the outlet. My phone is damaged and I need to replace it.
