Metro fibre technicians are *******

I am absolutely horified, from inception metro fibre has given me non stop poor service, the first time they came to install my fibre the technician forged my signature and didnt complete the job , i wasnt even at home i had someone sit in for me, up until this day almost six months later after complaining several times nobody came in to sort it out. Two days ago my kitten bit my cable i ordered a new one, the technician came the very next day but he used a dirty old cable that was clearly removed from someone elses home. I had ordered a new cable via metro fibre and was debited R180 from my bank. So i paid R180 for a dirty old cable and the technician walked away with my old cable , he was not supposed to take it cos it belonged to me damaged or not , so now he will splice that cable and go use it elsewer and take the new cable that another innocent person pays for. Real **** guys , please be alert
