No DSL Replacement

My ADSL has been offline since beginning of April, after logging a fault with Telkom and no response for over a week, had to call a couple of times before they told me that there's cable theft in my area. now they say they don't have an alternative for internet and will have to register a new contract (LTE) this is more expensive than the contract I have with them and they are not prepared to give me that option at the rate as per my contract with them. Its been a month now and no resolution has been made, I run a student's commune where this DSL is installed and some students have left, I am loosing money now because of Telkom's incompetence and poor customer service.
