Upgrade harassment calls & fees. App vs Private Purchase

The constant phone calls to "remind" me that I'm due for an upgrade since YEARS ago - is truly annoying. Even after my numerous requests to STOP phoning me. I KNOW I'm eligible for an upgrade! The Vodacom App is also more confusing than helpful. The recommendations / offers I get there... not appealing to me and seem even more obscure by the monthly payments - which does not seem to justify the costs.

At this time, seem that I'll just buy a new phone elsewhere (like Takealot / a store) and continue with a very basic Vodacom option. Seems like less hassle (and money) than having to deal with an upgrade via Vodacom :/

Best wishes.
