Bad service from Megasurf

I have been a loyal customer of Megasurf and now for the past few weeks I have had a very bad experience.<br> Megasurf sms'd me to let me know that the tower was damaged. a few days later I emailed Marius Jackson to ask what the progress was. He then rep**** and told me that the technician has a plan. 30min later I received a call from my Mother telling me that the technician Renier was there and busy on my home network and home pc, and not on the router that links up with the Megasurf tower. I did not give permission for him to do so. A few days later I received a invoice from wispweb for the outcome that I did not ask for. I told him we did not ask him to come out so we will not pay, he then phoned my Father and told him he will bliksem him if we do not pay. My father is a old man and very ill. I then contacted Megasurf's Marius Jackson and told him what was going on. He did not want to help me at all. 10min after Renier threatened my Father all of a sudden my router was offline and not connecting to the internet even my home network is offline. Coinsodence? I think not. I told him I am cancelling my account and now they want me to pay for another month. I already lost a week.
