Telkom's breach of contract

I took a contract with Telkom a month ago with the first payment due end of September. Day before yesterday I got a message that my services has been suspended due to no payment. I phoned but systems were offline. Got through this morning, they check my account, profusely apologise for the error and promises me that it would fixed before end of business today. Its not fixed, nobody can help me as the systems are offline, AGAIN. I got the contract for business purposes and am so sorry I ever did. I should have stayed on prepaid as I can't use my phone at all now, I can't communicate with my clients and Telkom does not care that they are in breach of contract. Doesn't give a twit.
