Data Upgrade - No Honouring of Contract (cont.)

I refer to my post here on the 4th of January 2018. The issue has not been dealt with as yet, I have no contact person to talk to and I'm unsure how to proceed.

I had taken a contract for a upgrade on my data sim with an i3 laptop included in the deal. Someone from Vodacom had called me to make the offer and had said I had to agree to it on the phone (it was a recorded phone call and she couldn't send me anything i writing beforehand) and that I couldn't such a good offer at the stores. When the laptop was delivered it was not an i3 as promised but a Celeron. This was something I saw on the box and phoned to request that it be replaced with the proper one. After speaking to many different departments (except Vodacom Rewards which is the one that I've been told actually called me), they've said that one their side it was captured as a Celeron. I of course asked for the original agreement (which would mean the recorded conversation according to Vodacom) and they've still failed to send this me or even say they can or would not.

They have collect the incorrect laptop a week and a half ago and had promised to get someone from Vodacom Rewards to call me to sort it out, but nothing has happened and I really am unsure how to proceed. I was called but was not left with a contact person to call back too and when I originally phoned the call centre and few department said they couldn't help me, I needed to speak to someone else and it just went in a very large circle.

Someone please help... Anyone out there. Stuck in a void.
