Product knowledge is lacking

At Ackermans Jacaranda centre i saw a mtn mifi router m30 for R350. I wanted to find out more about the router from mtn themselves. One mtn stores confirmed that this was a new wifi pocket router. Other mtn stores didnt have a clue of what i was talking about. Clearly they dont know their products. I was totally dumbfounded . Once again proves my point that mtn is totally *********** and useless. How can you do business in this.way ?
