I am being corned

I have been handed over to the lawyers by Jabba and last month I have paid them up and contacted the creditworx.They promise to send me the settlement letter as it takes 21 days to clear.okay I understood after 21 day have passed nothing and on the *** I get the message that I must not forget to pay R700 due today.I called them they said their lines are busy.I then call Jabba Connect and tell them that I have already paid them up R4100 outstanding,why am i getting this sms that I must pay R700.They say they is nothing they can do about it,I must call those guys and on their side it shows that I am owing them R3500.The agent from Jabba I spoke to is Nokuthula from collection side.Jabbba cannot interven as they are the ones that I bought a phone from.Which means I can be corned but Jabba wont help me. I do have the deposit slip<br> <br> 2nd Complain about Jabba<br> <br> Even jabba when I took the contract they promise to give me another phone after 1 year and after paying them off .I called them and they promise to get back to me withing 13 days but still nothing.It is way more than 13 days.
