Telkom -Poor Service

From October 2017 our Business Landline has been we had lodged the fault with Telkom and it takes them about 3 weeks to attend to the problem When they fix the Faults ,the landline works for about 2 or 3 days and then its down again. This has been on going from October last year, currently our lines are still down and we are losing a lot of Business as the telephone is the life blood of our business.Today they send me an SMS stating the line has been restored when it is still not working and and i had to log in another fault and the reference number is :223CNZ180118.This is ongoing.
