MTN Router - No Internet / Poor Service

I purchased a router with MTN, 10mbps @ R499 and received it 18 March 2022 and since receiving it I have had no internet access to date.

I have been running from pillar to post with each service centre sending me to another: * One minute, my sim card is not activated * Then it is not RICA * When I go to the stores (twice now) I am told that everything with sim is fine, then why do I still not have internet access? * I called Mondo as well (as instructed by an agent as they said issue may be the location of the device) to see if the address is correct they tell me they don't do address changes and I must got to a store

I am honestly very unhappy with the service from MTN as I have other products with them too. I would like to even cancel this new product because their service has been distasteful in solving this issue of mine
