MTN/SUPERSONIC ******* ROUTER

I received my hone router on Friday afternoon and as it this moment my router hasn't been activated. I started calling the call centre on Saturday but I have been dealing with a bunch of idiots to the extent that yesterday some agent asked if the router is plugged in and later droppwd my call after 17mins and didn't bother ro call back. On Saturday I was told my sim can't ne activated Rica because I have reached my limit of 10 sims, I requested for all the numbers on my ID and never got it! Another agent told me I am owing money and if I pay half then they will activate it! As I stated I am dealing 2with a bunch of idiots! How do I owe money on a new account with a router received the previous day??? I have aaked these clowns to come collect their router and as at yesterday I had requested to have a customer service supervisor call me but nothing happened. Router isn't activated till now. Why do you sell a product that you don't know how to activate????
