Pathetic service

I was on Family package, on Sunday I've requested multichoice to downgrade my package to Access and they told me to pay R150. 75 which I did immediately. Today they sent me an SMS to say that my account has been disconnected. The consulted who was assisting me today, she told me with an arrogance /attitude that the person who assisted me on Sunday did not tell me the terms of downgrading. This will only happen from next month. This is not my fault, if their consultant failed to do their job, they can't penalize me as the customer. It's either they reconnect my account or give me my money back
