Broadband SIM card still not activated after calling for week

I am really disappointed with the service from vodacom. I recently ordered fibre online and was giving interim LTE 100gb access until the fibre infrastructure gets installed in my area. The router was delivered to me on thursday but the SIM card was not activated contrary to the e-mail that was sent to me that the services has already been activated. I have been calling the fibre customer care center since thursday the 25th of April and my issue has not been resolved!! Everytime I speak to a new consultant I am being told my query has been logged with the back office and it will take 24-48 hours for the logged query to be assigned, more than 5 days later my SIM card has not been activated and I can't access internet. How difficult is it to activate a SIM card? Everytime I ask to speak to a manager and for my query to be escalated, I am being told I will be contacted back with feedback. I am still waiting for the feedback!! I am really really frustrated and have run out of patience. This is unacceptable
