Telkom refusing to fix faulty line

Without telkom line for more than a week. When we phoned we were told they will not fix the line we must get fibre. This after telkom told us in June 2019 by e-mail they will be replacing the line with fibre. When I phoned them after the mail they said no they cannot put in fibre????? We on a month to month I pay my account in advance. So I will be keeping you liable for my cost and I will not give you a month notice due to Telkom being in breach of contract.
