Open my line.

On the 14th of Jan I cancelled my contract and payed the outstanding amount. 7 months later I'm told that I owe vodacom R723.94 because my contract was not cancelled. Now my line has been closed for what?. This was my 1st time taking out a contract and I'm disappointed in how everything was handled. No notification was sent out to me advising me that my line will be blocked. The call centre agent then says she's not able to provide me with proof of communication that was sent out. This is by far the most disgusting service eva. I need my line to be reopened and I'm told that I will have to Pay the outstanding amount. You guys go on about your service but it stinks I must say.... Open my line or I will take legal action against you. I have all the proof that I cancelled and pay my account. If your sales agents messed up don't make it my problem.
