Faulty dive and won't take it back and replace with working device

I have received my two Mercer Guru Pro and two Huawei routers from Ram today. 1. THE ROOTERS ARE STILL NOT ACTIVATED 2. THE ONE MERCER GIRU PRO LAPTOP TABLET IS FAULTY ONCE YOU TRY TO SET UP THE PASSWORD IT DOESN'T GO ANY FURTHER. IT STAYS ON PLEASE WAIT A MOMENT FOR OVER 3 OURS! I PHONED THE CUSTOMER SERVICE AND THE LADY ADVICED THAT I NEED TO TAKE IN THE MERCER FOR THEM TO SEND IT IN AND REPAIR THE PROBLEM!!!! I HAVE JUST RECEIVED IT. I DON'T WANT IT REPAIRED I WANT IT SWAPED OUT AND REPLACED WITH A WORKING MERCER. IF NOT I AM CANCELING BOTH THE CONTRACTS I HAVE TAKEN AS YOU CAN'T EXPECT ME TO RECIEVE A FAULTY LAPTOP AND THEN TO SEND IT FOR REPAIRS THAT IS BEYOND UNACCEPTABLE!!! I ALSO WANT BOTH OF MY ROUTERS TO BE ACTIVATED! HOW DOES VODACOM EXPECT YOU TO BE HAPPY WITH A FAULTY DIVICE AND YOU NEED TO SEND IT FOR REPAIRS.
