Infrastructure Upgrade is actaully Downgrade

Well so I receive a message from Telkom on 8 February that there is an Infrastructure Upgrade in my area. Well Telkom I have news for you, please downgrade back to what it before, because since your upgrade I have a very bad internet connection, Reported it several times, and everytime your competent technicians close the calls without resolving the problem. Tonight I get home and my landline is down as well. You are the worst service provider in this country. The moment I get Cellular Fibre in my area I am cancelling the contract, because I am paying a service which I am not getting. PS I upgraded to 4mg line and found out that the upgrade was never synchronised on the exchange. At this moment i do not want to hear the work Telkom because it gets my blood boiling. My 3G is more reliable and that does not say much for you, because signal in my area is very very bad.
