NO INTERNET CONNECTION

This the last time am writing to Vodacom , I have been calling to inform them for month that their router is not working , always its connected without internet . I have been writing to this platform form several times . I need to use this router for work and school with no help am paying every month for some thing that doesn't benefit me I even took contract from another service provider which is working perfectly . The last time I didn't pay them for a month they blocked my personal sim card because its also Vodacom number and even took me to MBD attorneys , how fair is that? this time its fine they can do whatever they want to to do I wont pay my contract blacklist me for all I care , its better than paying for connected without internet everyday .
