Bad Service technical

We phoned several times due to a fault on our lines since Thursday 19th Of October 2017 twice we received a message saying that the issue have been resolved but phones still not working. Every time we phone they report a new fault and don't hurry the process to say that it has not been resolved. We losing business due to no working lines. They suppose to come today but still nothing. Will not recommend any telkom products or services to anyone if this is not resolved today. Can't believe they handle a urgent and priority business client like this.
