Vodacom Terrible Management Accounts

Terrible management ! I had a contract with Vodacom 3 years ago. A few weeks ago I went to Vodacome store to open a new contract. They told me that I am BLACKLISTED ! When investigating, they said my previous account had a balance of R2.00 not Paid. YES, R2. My previous account was debited automatically and they DID NOT debit me properly. This is not my fault ! I will open a case to Vodacom if my name is not clear. Recently I had to open some other account and I was declined. Now I am aware why ! This is causing great issues and I will send an attorneys letter if not resolved within 7 days. Idiots !
