Bad ********* unprofessional behaviour

I had a cell phone contract with Vodacom which I fell a few payments behind, I called their collections department to request the total amount due and settlement , all right and well they transferred me to their attorneys which I spoke to one of their agent and they gave me a settlement amount which I paid on the 24th of January. Last week I tried calling their attorneys (Vodacom) no response or reply, I call Vodacom collections they transferred me and I advised payment was made they informed me they will let me know in 2to 3 days. Today I get a call from a very rude and arrogant consultant who hung up on me while I was talking. He told me my account my still owning and I must just pay and he hang up when I asked him to get the voice call recording which I was advised on the amount to pay which was discounted which I paid he said he will do no such I must just pay. I'm very Disappointed with Vodacom for this unprofessional collection agency they are using who still Rob people and still using primitive ways of collections.
