3 Months and still waiting for a collection of a faulty device

I upgraded my data line with Vodacom on the 01 June 2022, and the upgrade came with the home router. The router was delivered, but it was not connecting. I did sim swap 2 times as advised by the consultants because even my sim card stopped working when they did the upgrade. Even now my sim card is not working. I called the after sales on the 01 June 2022 and they said they logged the call for the device to be collected from my address and my upgrade will be reversed. I was further advised that I should not take the device to the Vodacom shop. I have been calling Vodacom every week since the 01 June and I'm told they have escalated my query to the collection Department every week I call. Even today I was told the same thing. it is now 3 months, I am paying for this account, but I'm using the data. I have been with Vodacom for more than 20 years and today I receive the treatment I am getting.
