Vodacom can do better, but currently I'm not happy😒

I went to Vodacom Ballito mall to check on black Friday specials since my 1TB was gonna expire the same November, with the consultant we concluded that I'll do the order online since they have same offers. Later when I had to conclude my choice online I find that the in-store has blocked my online application, when I called them they said it's not them. All in all I want to say I lost the black Friday offer because of blockage, my current contract was then not canceled and I'm paying a lot of money now on. There's a lot happening with Vodacom I'm even concidering trying other networks, even with my 2nd contract I have issues as well.
