Cancelled account in April, Hard locked phone

I Cancelled my account in April 2015 at the vodacom shop in Kollonnade. Again they deducted an amount out of my bank, the agent told me it was a cancellation fee. Next month they tried again and I stopped the debit order. I have tried 9 times to cancel the contract after that and yet now they have hard locked my phone.<br> <br> I have sent emails, live chats, phoned and went to the dealer and yet nothing.... I am at my whits end. I have been a proud vodacom supporter since I had my first phone. This is how they handle their clients and it is not acceptable.<br> <br> When I asked to speak to a manager the guy hung up on me. This is my last resort and if this fails I will take my business elsewhere.
