Free Router, catch is no internet, and your landline number will not work either

I was offered a new deal to safe costs by having my LTE landline converted to a separate sim as land line and separate for internet as I needed a faster internet connection. Everything was done, a new router delivered with Sim card. NO internet. A week later internet for two days then again NO internet. I asked that they come collect the router and their sim card as it falls within my right to cancel the service. I eventually got a response back that no router or sim was ordered or delivered???? Now I have the router without internet, put back in the box and awaiting Telkom to collect. Now I have no landline either for who knows what reason. Trying to get hold of anyone is impossible. And if I want to go in store, I got told I can only go to the store in the Mall of Africa no other shops will assist.
