Activation of Sim Card, wrong sim delivered

I have purchase a Huawei Router R207 with a 2 gig data bundle received it on the 6th January, and ever since phoning Vodacom Activation to active the sim card, every time they tell me the card is activated, after spending 2 hours on the phone trying to find out what the problem is, this morning they discovered that the sim card nr they delivered Is not the same as on the system, so the wrong sim card was delivered to me the nr does not correspond no wonder nothing is working. the informed me that the technical department must first request a sim swap and can take another 48-72 hours. this is unacceptable there fault why must I wait another 3 days, the month is almost over and not even had joy of the Router. please I need someone to help me the person that helped me was not very keen to speed up the query I have to wait.. WHY MUST I WAIT 3 DAYS. I ordered this by Phone on the 21 December 2015, and was only delivered on 6 January 2016. now a month and still struggling. BAD SERVICE FROM VODACOM DIRECT.
