LTE device - Sim registered no Internet Access

Received our LTE device on the 10 Oct. Very excited to test the proposed fast internet speeds. Arrived home and no internet access. Went back to the store, they did a sim swop and still no internet access. Logged a call with the Telkom Mobile Data Connections and was advised that the problem will be resolved in 72 hours. It's been 72 hours still no internet access. Sim is registered. Telkom cannot advise me when this will be resolved.<br> <br> Paying for a service which is not working.
