Telkom unfair disconnection and theft

My account was suspended due to late payment. The payment however was made 15 Feb. They actually took off Jan and Feb that day. Today is the 3rd of March and my account was suspended due to non payment. When I phoned to ask what is wrong they say ' we can see the payment of 15th Feb, but it has not been allocated and that is why my account still shows that it is in arrears. And that I now owe R799 at the end of this month. Not sure how the hell this is possible, because the payment was made in Feb. My only payment outstanding is now for end of march which is R199. As per my normal monthly payments. How can a payment from 15th FEB still not show as reflected????? And now my line is disconnected. I feel this is theft? Can TELKOM please assist me with this and get my line back as well as give my my TRUE outstanding amount. I feel that if R799 is deducted from my account end of March that it is in my right to sue Telkom for theft, at the least.
