bad attitude & poor service from Sharon Buthelezi

I have been working with this lady regarding my cellphone contract. She promised to get back to me once I finalised my payment arrangements with Vodacom. I have two accounts with Vodacom and I have just finished paying my first contract with them, the arrangement was to then open the number because it was suspend. Now my second contract is still in arrears but I was told that they will not take my account to legal, all I have to do is to continuing paying for the contract. On the 17th of March I received am sms stating that i have been sent to Legal. I then spoke to Sharon on 18th of March and she said she will get back to me because they were offline, while i was at the Vodacom shop in Rustenburg. I then paid R300 at an fhb on the 18th after talking to her (Sharon). She finally called on the 20th of March and then asked me what my issues were and that I should explain everything again to her after we spoke and made arrangements on the 18th. She then began to be rude and had a bad attitude after I asked why my account has now gone up even after I paid R300. All I wanted was an explanation and to understand why that had happened after we spoke on the 18th.
