Subgrade internet service

I'm highly annoyed and frustrated with Telkom. My internet line is still down! A new router was bought yet I still have no connection, D-Link message reads no connection when trying to set up. Your only saving grace is the impeccable service and assistance I have received from your call center who have gone out of their way to try and assist. Less could be said for Greenstone mall store who were uncooperative and unhelpful! It's definitely time to rethink my internet service provider and to look for alternatives! Not impressed Telkom!
