Bad Practice Service, Advertising, and Onboarding

I upgraded to a data sim that should have been delivered by RAM couriers. I enquired 3 x with the Vodacom shop. At the start of December, my present SIM got de-registered. My number of twenty years "cancelled". Trying customer service, but I was told it can only be reversed in a month. However, the data service got activated on my profile, but the SIM does not work on a phone, a router is required. Nothing of which is explained (at any time) when purchasing the deal. I am being charged already, but I can't use the service as I have a router, and nor do I want/ need one.

So, now I am stuck with a product that does not work, no phone number, and no way to get customer service to do anything about it. What service provider would deregister someone's phone number? No matter how a product is structured, it does not make sense to cancel a phone number. This is anti-retention, it's actively getting rid of a customer, and it does not make sense.

I have also sent an email last week to explain the situation, but no response, nothing. All I am left to do is cancel the debit order and not be a customer anymore. Not that you would notice...
