Becareful of contract migration to fibre

The poor consultant who I just blasted from "mobile" my apology. The answer of Fibre and Mobile divisions are not the same is not satisfactory. Your offer to me was "migrate your lte contract to fibre". Telkom offered that and there is email proof. To all lte clients of Telkom, be careful. The sales pitch is awesome to the point that when I queried the router and returning it I was told not to worry because it falls away to the new fibre contract. According to the consultant from customer care, after 6 calls, "just cancel contract", fibre takes over. Now after the fibre being fitted there are additional costs and penalties. I am sure this is called misrepresentation..... the fact that Telkoms internal divisions dont communicate is not the clients fault. Managers dont take calls! The minute a consultant ends online chat, the conversation disappears, and customer care numbers oh dear..... According to recordings covid has wiped those too. My anger is rife, so I intend to complain until 1000s of people have read this and other complaints..... it wont save me money i am billed for but hey it will make me feel abit better. Since the recording of the fibre is now non existant, and consultant cannot be traced does that mean our contract is still valid? Can you prove it based on all the non existant people at Telkom?
