Breach of contract, no service 3 months

I have been with Telkom for just under a year now and since May, I have not received any service from them. In the first week of May 2018 , we had technicians come to our road and install fiber, since then we have not had any internet connection, we assumed it was due to the upgrade and left it for the month, they left the last week of May and with the line still down, we then decided to call Telkom for the first time on May 24th 2018. We spent 58 minutes on hold and then when we got through, went through a phone call lasting 60 minutes with a technical agent, to then be told, she will raise a case and send a technician out to us. We were told they would call within the week to arrange a day to come. A week later,we decided to contact Telkom on facebook, they responded a day later, saying a case was opened, then responded later that day,saying problem resolved it was not. Fast forward a month to June 24th 2018, no phone call, no technician, we then went into the store and raised it with an agent in store, he was great, he filed many cases including one to cover the account and have the account recalculated so we can be credited for lost service eventhough we had paid for it for the 2 months before, he said he would call in 48 hours with an update and a technician would call in a week. NOTHING! 2 weeks later we get an sms saying, issue resolved. Fast forward a month to today, we stopped the payment for this month as we are getting no where and telkom then have the audacity to send us an SMS 3 days later, saying we were suspended due to non payment, they have been breaching contract for 3 months and now we are cut off with no resolution, I am sick and tired of the back and forth and want this to be resolved.
