I REGRET THE DAY I TOOK A CONTRACT WITH VODACOM

Vodacom deducted R109 from my bank account whereas I canceled the contract after paying them the contract for 24 months in March. I regret the day I took a contract with Vodacom sies. Agent Venice or Denise I'm still waiting for a call back regarding this matter. She promised to phone me two weeks back that I will get my money back and I will get a paid up letter. Vodacom is messing up with my credit profile as it still shows that I have an account with you. I NEED THE PAID UP LETTER. Vodacom needs to deal with the agent (Naidoo) that did not cancel my contract to prepaid. Why must I be liable for that agent's incompetency?
