Dstv delivered 6 routers instead of 1 and taking forever to rectify their mistake

2 weeks ago I wrote a review that dstv delivered 6 internet routers at my home instead of 1, they called and told me courier will come and collect the extra routers. A week later after they're call I'm still stuck with 6 routers and a huge bill that I'm not will to pay. I'm not gonna pay for incompetence of Multichoice because I feel like they're intentionally delaying the process of fetching routers before billing date so tbst they can take my money.
