Dstv is bulling customers instead of rectifying their mistakes

This is my 4th complain about dstv delivering 6 wifi routers at my home instead of one. Everytime I post about this i get a call from them promising that they will resolve this month later im still stuck with 6 wifi routers, they haven't collected them as promised on calls and emails. Now they sent me an sms telling me to pay R1,700 or they will disconnect my dstv compact subscription. I'm been bul**** to pay for routers that were mistakenly delivered to my home because of their system error. I've tried everything to get them to correct thus mistake but it seems like they not willing they rather bully me into paying for things that I didn't order instead of fetching routers and fixing my billing account. I even went to their randburg dstv walk center instead of helping me they told me to go back home and wait for courier to come fetch routers. A month later no courier just them sending me reminders to pay those routers or face been disconnected. After over15 years been a dstv customer im defeated , imagine ending up with almost R2000 bill whilst you're a compact customer.
