Bad service

I have had the worst experience regarding MTN service, since August when i got the router the service has never been active, i was advised that the home router works at the address i registered when doing the application but somehow someone managed to mess that up and put my work address where the router was delivered as my main address so whos fault was that certainly not mine and if that is the case am i supposed to travel with a router to the office everyday so that i can make use of the services. I called the call center and spoke to a lady who told me i must go to the MTN branch i refused because when they were selling the product it was done telephonic and i submitted all my documents when it was delivered, then i called again and spoke to a gentleman who promised to have it fixed and it would be working in a couple of hours but that never happened. I purposely did not leave money in my account for them to debit because i cant pay for a service i am not getting and i have sent various emails to cancel or to come and collect their router since it was obvious i would not be happy with the service but no assistance or reply, now they have decided to hand me over to attorneys so what exactly am i paying for because i am sure even on their system it should show that no data has ever been utilized from that router.
