Worst Fibre Ever! Telkom BOLTSPEED? I have no connection!

I had business fire installed on 7 June 2018. We took out a 20mps package. Since the 7ht of June we have had intermittent issues with connectivity going on and off during the course of the day. Tuesday we were down for most of the day, yesterday we were down again. It was so bad that I could not pay salaries as I had no internet! This morning fibre was down again for 4 hours. Yet again I emphasize that this is a business line! We are reliant on it. You call centre has re-set this line about 50 times in the last week. Then told me there was an issue with the network and the fault hat to be sent to the networking department for the to re-design the line. This is affecting my business and productivity and I can can longer listen to your call centre recording "How can we improve our service".... I get no service!! Also telling me to go into a branch for some Intergrate Data Sim Card to help while I am off. Telkom told us it is a stable connection - BOLTSPEED! Telkom market fibre above adsl as it is more "stable" etc. Well at this point in time I wish I would go back to ADSL. I have logged this fault over 48 hours ago with no phone call from Telkom! I gather from how busy your call centre is that I am not the only one experiencing problems with fibre. Installation from OpenServe was prompt, professional and a great experience. They have been back here twice since instillation to try and assist me and ensure the problem is not on their side. Having Telkom as the ISP - nightmare! Either you allow me to exit my contract, or you fix the problem! Clearly you guys have a MASSIVE network problem.
