Bad Service!

So frustrating paying for a certain line speed and not getting what you pay for! The worst of all is they have absolutely no help line after hours or on weekends. I have left messages on both whatsapp numbers, tried to phone and left messages on facebook, but no one would bother to phone when back in the office to follow up. Im paying for a 60mbps download speed and on weekends im getting 6mbps! I dont even mind paying a little extra for a better line, I just want to be helped. Very bad customer service!
